AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
The FAA proposes to supersede an existing airworthiness directive (AD) for Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, “Parallel Valve” reciprocating engines, with certain Engine Components, Inc. (ECi) cylinder assemblies, part number (P/N) AEL65102 series “Titan,” installed. That AD currently requires initial and repetitive visual inspections and compression tests to detect cracks at the head-to-barrel interface, replacement of cylinder assemblies found cracked, and replacement of certain cylinder assemblies at new, reduced times-in-service. This proposed AD would require the same actions, but for an expanded population of cylinder assemblies. This proposed AD results from reports of 10 additional cylinder head separations since issuing AD 2008-19-05, on cylinder serial numbers not listed in that AD. We are proposing this AD to prevent loss of engine power due to cracks at the head-to-barrel interface and possible engine failure caused by separation of a cylinder head, which could result in loss of control of the aircraft.
DATES:
We must receive any comments on this proposed AD by September 28, 2009.

Discussion
The FAA proposes to amend 14 CFR part 39 by superseding AD 2008-19-05, Amendment 39-15672 (73 FR 53105, September 15, 2008). That AD requires initial and repetitive visual inspections and compression tests to detect cracks at the head-to-barrel interface, replacement of cylinder assemblies found cracked, and replacement of certain cylinder assemblies, at new reduced times-in-service. That AD was the result of reports of 45 failures with head separations of ECi cylinder assemblies. That condition, if not corrected, could result in loss of engine power due to cracks at the head-to-barrel interface in the cylinder assemblies and possible engine failure caused by separation of a cylinder head, which could result in loss of control of the aircraft.
Actions Since AD 2008-19-05 Was Issued
Since AD 2008-19-05 was issued, we received reports of 10 additional cylinder head separations, on cylinder serial numbers not listed in that AD. To date, there have been a total of 55 head separations resulting in engine shutdowns and emergency landings in airplanes and helicopters.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For that reason, we are proposing this AD, which would require initial and repetitive visual inspections and compression tests to detect cracks at the head-to-barrel interface, replacement of cylinder assemblies found cracked, and replacement of certain cylinder assemblies, at new reduced times-in-service. The proposed AD would require:Start Printed Page 37956
- Determining if Group “A” or Group “B” ECi cylinder assemblies, P/N AEL65102 series “Titan,” with cylinder head P/N AEL85099, are installed on your engine.
- For any Group “A” cylinder assembly, performing initial and repetitive visual inspections and compression tests, and replacement not later than 2,000 operating hours time-in-service (TIS) or within 25 operating hours TIS if the cylinder assembly exceeds 2,000 operating hours TIS on the effective date of the proposed AD.
- For any Group “A” cylinder assembly installed in a helicopter, performing the same initial and repetitive visual inspections and compression tests, but replacement not later than 1,500 operating hours TIS or within 25 operating hours TIS if the cylinder assembly exceeds 1,500 operating hours TIS on the effective date of the proposed AD.
- Expanding the serial numbers affected of Group “B” cylinder assemblies, and performing the same initial visual inspection and compression test, and replacement not later than 350 operating hours TIS or within 25 operating hours TIS if the cylinder assembly exceeds 350 operating hours TIS on the effective date of the proposed AD.
Costs of Compliance
We estimate that this proposed AD would affect 18,000 ECi cylinder assemblies installed in aircraft of U.S. registry. The visual inspection and compression tests would take about 4 work-hours for each engine. An individual cylinder replacement would require $1,100 for parts and 6 work-hours. Lycoming engines with a set of 4 ECi cylinders would require 12 work-hours for the cylinder replacement. Lycoming engines with a set of 6 ECi cylinders would require 16 work-hours for the cylinder replacement. We estimate 18 percent of the affected population of cylinders would be replaced. We estimate the total cost of the AD to U.S. operators to be $10,172,000. Our estimate is exclusive of any possible warranty coverage.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that the proposed AD:
1. Is not a “significant regulatory action” under Executive Order 12866;
2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
3. Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD. See the ADDRESSES section for a location to examine the regulatory evaluation.

The Proposed Amendment
Under the authority delegated to me by the Administrator, the Federal Aviation Administration proposes to amend 14 CFR part 39 as follows:
Start PartPART 39—AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
[Amended]2. The FAA amends § 39.13 by removing Amendment 39-15672 (73 FR 53105, September 15, 2008) and by adding a new airworthiness directive to read as follows:
Engine Components, Inc. (ECi): Docket No. FAA-2008-0052; Directorate Identifier 2008-NE-01-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive comments on this airworthiness directive (AD) action by September 28, 2009.
Affected ADs
(b) This AD supersedes AD 2008-19-05, Amendment 39-15672.
Applicability
(c) If your engine has not been overhauled, or not had any cylinder assemblies replaced since new, no further action is required.
(d) This AD applies to the Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, “Parallel Valve,” reciprocating engines listed in Table 1 of this AD, with ECi cylinder assembly, part number (P/N) AEL65102 series “Titan,” and with cylinder head, P/N AEL85099, installed.
(1) The applicable cylinder assembly serial numbers (SNs) are SN 1138-02 through SN 35171-22, (referred to in this AD as Group “A” cylinder assemblies); and
(2) SN 35239-01 through SN 42179-30 (referred to in this AD as Group “B” cylinder assemblies).
(3) The cylinder assembly P/N is at the crankcase end of the cylinder assembly, and might be difficult to see. As a guide in determining if your cylinder assemblies are affected, all affected cylinder assemblies have cylinder head P/N AEL85099. The cylinder head P/N is at the top of the cylinder head, near the intake and exhaust valve springs, and is easier to locate than the cylinder assembly P/N.
(4) The set of numbers appearing on the cylinder, above and to the left of the SN, in the form of “123456” is not used for determining applicability.

(e) This AD results from reports of 10 additional cylinder head separations since issuing AD 2008-19-05, on cylinder serial numbers not listed in that AD. We are issuing this AD to prevent loss of engine power due to cracks at the head-to-barrel interface in the cylinder assemblies and possible engine failure caused by separation of a cylinder head, which could result in loss of control of the aircraft.
Compliance
(f) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Engines Overhauled or Cylinder Assemblies Replaced Since New
(g) If your engine was overhauled or had a cylinder assembly replaced since new, do the following:
(1) Before further flight, inspect the maintenance records and engine logbook to determine if the overhaul or repair facility used ECi cylinder assemblies, P/N AEL65102, with cylinder head, PN AEL85099, with a SN 1138-02 through SN 35171-22, or a SN 35239-01 through SN 42179-30, installed.
(2) If the cylinder assemblies are not ECi, P/N AEL65102, no further action is required.
(3) If the cylinder assemblies are ECi, P/N AEL65102, and if the SN is not listed in this AD, no further action is required.
(4) If the cylinder assemblies are ECi, P/N AEL65102, and if the SN is listed in this AD, do the following:
Group “A” Cylinder Assemblies
(i) For Group “A” cylinder assemblies:
(A) Perform an initial visual inspection as specified in paragraphs (h) through (i) of this AD, and an initial compression test as specified in paragraphs (j) through (n) of this AD, within the next 10 operating hours time-in-service (TIS), if the cylinder assembly has 350 or more operating hours TIS on the effective date of this AD, but fewer than 2,000 operating hours TIS.
(B) Perform an initial visual inspection as specified in paragraphs (h) through (i) of this AD, and an initial compression test as specified in paragraphs (j) through (n) of this AD, within the next 10 operating hours TIS, or before exceeding 350 operating hours TIS, whichever occurs later, if the cylinder assembly has fewer than 350 operating hours TIS on the effective date of this AD.
(C) Replace cylinder assemblies installed in helicopter engines within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 1,500 operating hours TIS or more on the effective date of this AD.
(D) Replace cylinder assemblies installed in airplane engines within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 2,000 operating hours TIS or more on the effective date of this AD.
(E) Perform repetitive visual inspections as specified in paragraphs (h) through (i) of this AD, and repetitive compression tests as specified in paragraphs (j) through (n) of this AD, within every 50 operating hours TIS.
(F) Replace cylinder assemblies installed in helicopter engines that pass the visual inspections and compression tests, no later than 1,500 operating hours TIS after the effective date of this AD.
(G) Replace cylinder assemblies installed in airplane engines that pass the visual inspections and compression tests, no later than 2,000 operating hours TIS after the effective date of this AD.
Group “B” Cylinder Assemblies
(ii) For Group “B” cylinder assemblies:
(A) Perform an initial visual inspection as specified in paragraphs (h) through (i) of this AD, and initial compression test as specified in paragraphs (j) through (n) of this AD, within the next 10 operating hours TIS.
(B) Replace the cylinder assembly within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 350 or more operating hours TIS on the effective date of this AD.
(C) Replace cylinder assemblies that pass the initial visual inspections and compression tests, before exceeding 350 operating hours TIS after the effective date of this AD.
Visual Inspection
(h) Visually inspect each cylinder head around the exhaust valve side for cracks or any signs of black or white residue of combustion leakage from cracks.
(i) Replace cracked cylinder assemblies before further flight.
Cylinder Assembly Compression Test
(j) Perform a standard cylinder differential compression test.
(k) During the compression test, if the cylinder pressure gauge reads below 70 pounds-per-square-inch, apply a water and soap solution to the side of the leaking cylinder, near the head-to-barrel interface.
(l) Replace the cylinder assembly before further flight if air leakage and bubbles are observed on the side of the cylinder assembly, near the head-to-barrel interface.
(m) Repair or replace the engine cylinder assembly before further flight if the cause of the low gauge reading in paragraph (l) of this AD is from leaking intake or exhaust valves, or from leaking piston rings.
Prohibition of ECi Cylinder Assemblies Affected by This AD
(n) After the effective date of this AD, do not install any ECi cylinder assembly, P/N AEL65102, with cylinder head, P/N AEL85099, and with SN 1138-02 through SN 35171-22, or SN 35239-01 through SN 42179-30, onto any engine, and do not attempt to repair or reuse these ECi cylinder assemblies.
Alternative Methods of Compliance
(o) The Manager, Special Certification Office, has the authority to approve alternative methods of compliance for this Start Printed Page 37963AD if requested using the procedures found in 14 CFR 39.19.
Special Flight Permits
(p) Under 14 CFR part 39.23, we will not approve special flight permits for this AD for engines that have failed the visual inspection or the cylinder assembly compression test required by this AD.
