Discussion

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2019-0019, dated January 30, 2019 (EASA AD 2019-0019) to correct an unsafe condition for Leonardo S.p.A. (formerly Finmeccanica S.p.A., AgustaWestland S.p.A.) Model AW169 and AW189 helicopters with T/R actuator part number (P/N) 6F6730V00331 and a serial number (S/N) up to 489 inclusive, except those marked with “SB 67-0007,” installed. EASA advises of reports of non-conformities of the T/R actuator back-end input lever, indicating incorrect orientation of the lever with its trunnion locking pin.

EASA states this condition could lead to de-bonding and slippage of one of the two redundant lever bearings and possibly affect the functionality of the T/R actuator. A batch of T/R actuators was identified that may be also affected. Accordingly, EASA AD 2019-0019 requires one-time conformity checks of certain T/R actuator input levers, sending information and photos to Leonardo S.p.A., and depending on inspection findings, marking a part, inspecting the bonding of each bearing, and replacing the T/R actuator. EASA AD 2019-0019 also prohibits installation of the affected parts.

FAA's Determination

These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA of the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all information provided by EASA and determining the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs.

Related Service Information Under 1 CFR Part 51

UTC Aerospace Systems (Collins Aerospace) has issued Service Bulletin 67-0007, Basic Issue, dated January 17, 2019 (SB 67-0007). SB 67-0007 specifies verifying that the width of the bearing circular collar of the input lever is within the allowable limits of 4 ±0.3 mm, and checking the input lever pin head, and the nut and cotter pin of the intermediate bolt for proper installation. Depending on the inspection results, SB 67-0007 specifies replacing the T/R actuator, or marking the input lever and sending its completed registration form and photos of each side of the input lever to Leonardo Helicopters. SB 67-0007 is incorporated by reference in this AD.

SB 67-0007 is attached as Annex A to Leonardo Helicopters Alert Service Bulletin (ASB) No. 169-129, dated January 30, 2019 (ASB 169-129), for Model AW169 helicopters, and Leonardo Helicopters ASB No. 189-220, dated January 30, 2019 (ASB 189-220), for Model AW189 helicopters. ASB 169-129 and ASB 189-220 are not incorporated by reference in this AD.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Other Related Service Information

Leonardo Helicopters has issued ASB 169-129 and ASB 189-220. This service information refers to SB 67-0007 for instructions to inspect certain part-numbered and serial-numbered T/R actuator input lever assemblies. Depending on findings, this service information specifies marking the input lever, inspecting the bonding of each bearing, and replacing the T/R actuator on a specified compliance time schedule based on findings. This service information also specifies sending information, photos, and certain T/R actuators to Leonardo Helicopters.

AD Requirements

For Model AW169 and AW189 helicopters with a T/R actuator P/N 6F6730V00331 and an S/N up to 489 inclusive, except those marked with “SB 67-0007,” installed, this AD requires inspecting the T/R actuator input lever assembly by determining if the width of the bearing circular collar of the input lever is within allowable limits, and inspecting for proper installation of the pin and of the intermediate bolt's nut and cotter pin. This AD requires reporting certain information and photos to Leonardo S.p.A. Based on the inspection outcome, this AD requires marking “SB 67-0007” on the input lever, inspecting each bearing for correct bonding, and removing the T/R actuator from service at different compliance times. This AD also prohibits installation of affected T/R actuators.

Differences Between This AD and the EASA AD

The EASA AD requires returning a removed T/R actuator to Leonardo Helicopters, whereas this AD does not. Depending on the inspection results of the T/R actuator input lever assembly, one of the compliance times to replace the T/R actuator in the EASA AD is 200 hours TIS or 2 months, whichever occurs first. This AD requires removing the T/R actuator from service within 60 hours TIS for the same inspection results instead.

Costs of Compliance

The FAA estimates that this AD affects 10 helicopters of U.S. Registry. Labor costs are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs in order to comply with this AD.

Inspecting the T/R actuator input lever assembly takes about 1 work-hour, and reporting information and photos to Leonardo S.p.A. takes about 1 work-hour, for an estimated cost of $170 per helicopter and $1,700 for the U.S. fleet. Marking a part takes a minimal amount of time for a nominal cost. Replacing a T/R actuator takes about 6 work-hours and parts cost about $20,000, for an estimated cost of $20,510 per helicopter.

According to Leonardo Helicopter's service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage by Leonardo Helicopters. Accordingly, the FAA has included all costs in the cost estimate.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

Justification for Immediate Adoption and Determination of the Effective Date

Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for “good cause” finds that those procedures are “impracticable, unnecessary, or contrary to the public interest.” Under this section, an agency, upon finding good cause, may issue a final rule without seeking comment prior to the rulemaking.

An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies foregoing notice and comment prior to adoption of this rule because the initial inspection requirements must be completed within 30 hours time-in-service. Therefore notice and opportunity for prior public comment are impracticable and contrary to public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the reason stated above, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days.

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.

The FAA is 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

The FAA determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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, I certify that this AD:

1. Is not a “significant regulatory action” under Executive Order 12866, and

2. Will not affect intrastate aviation in Alaska.

The FAA prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
