AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to Raytheon Aircraft Company (Raytheon) Models
E33, F33, G33, E33A, F33A, E33C, F33C, C35, D35, E35, F35, G35, H35,
J35, K35, M35, N35, P35, S35, V35, V35A, V35B, V35TC, V35ATC, V35BTC,
36, A36, A36TC, B36TC, 50, B50, C50, 95-55, 95A55, 95B55, 95C55, D55,
E55, 56TC, A56TC, 58, 58TC, 95, B95, B95A, D95A, and E95 airplanes. The
proposed action would require checking the interior cabin door handle
and the interior utility door handle for proper locking, and if the
handles do not lock, re-installing the door handles correctly for the
lock to engage. Reports of the interior utility and interior cabin door
handles opening without depressing the lock release button prompted the
proposed action. The actions specified by the proposed AD are intended
to prevent unintentional opening of the interior cabin side door and
the interior utility door while in flight, which if not detected and
corrected, could result in injury to passengers.
DATES: Comments must be received on or before February 21, 1997.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Assistant Chief

Events Leading to the Proposed Action
Reports received from nine owners/operators of Raytheon Models E33,
F33, G33, E33A, F33A, E33C, F33C, C35, D35, E35, F35, G35, H35, J35,
K35, M35, N35, P35, S35, V35, V35A, V35B, V35TC, V35ATC, V35BTC, 36,
A36, A36TC, B36TC, 50, B50, C50, 95-55, 95A55, 95B55, 95C55, D55, E55,
56TC, A56TC, 58, 58TC, 95, B95, B95A, D95A, and E95 airplanes show that
the interior side cabin door and utility door may open unintentionally
because the door handle's lock release button may not catch due to
improper installation. If this problem is not discovered and corrected,
a passenger or crew member could lean his/her hand down on the
supposedly locked door handle and the door would open without warning.
Related Service Information
Raytheon has issued Service Bulletin No. 2693, Issued May 1996
which specifies inspecting the airplane's interior side cabin door and
utility door handles for locking and proper installation.
Explanation of the Provision of the Proposed Action
After examining the circumstances and reviewing all available
information related to the incidents described above, the FAA has
determined that AD action should be taken to prevent unintentional
opening of the interior cabin side door and the interior utility door
while in flight, which if not detected and corrected, could result in
injury to passengers.
Since an unsafe condition has been identified that is likely to
exist or develop in other Raytheon Models E33, F33, G33, E33A, F33A,
E33C, F33C, C35, D35, E35, F35, G35, H35, J35, K35, M35, N35, P35, S35,
V35, V35A, V35B, V35TC, V35ATC, V35BTC, 36, A36, A36TC, B36TC, 50, B50,
C50, 95-55, 95A55, 95B55, 95C55, D55, E55, 56TC, A56TC, 58, 58TC, 95,
B95, B95A, D95A, and E95 airplanes of the same type design, the
proposed AD would require a certified pilot checking the interior side
cabin door handle and the utility door handle for correct locking
operation of the handle. If the handle opens the door without pushing
the handle's lock release button, prior to further flight, the proposed
AD would require a licensed airframe mechanic to correct the door lock
by removing the handle, and installing the handle so that
[[Page 67506]]
the handle lock release button locks the door.
Cost Impact
The FAA estimates that 19,000 airplanes in the U.S. registry would
be affected by the proposed AD, that it would take approximately 2
workhours per airplane to accomplish the proposed action, and that the
average labor rate is approximately $60 an hour. Based on these
figures, the total cost impact of the proposed AD on U.S. operators is
estimated to be $2,280,000. The FAA has no way to determine the number
of owners/operators with affected airplanes who have not inspected or
re-installed the door handles.
Regulatory Impact
The regulations proposed herein would not have substantial direct
effects 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. Therefore, in
accordance with Executive Order 12612, it is determined that this
proposal would not have sufficient federalism implications to warrant
the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated,
will not have a significant economic impact, positive or negative, on a
substantial number of small entities under the criteria of the
Regulatory Flexibility Act. A copy of the draft regulatory evaluation
prepared for this action has been placed in the Rules Docket. A copy of
it may be obtained by contacting the Rules Docket at the location
provided under the caption ADDRESSES.

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend
part 39 of the Federal Aviation Regulations (14 CFR part 39) as
follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 USC 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
(AD) to read as follows:
Raytheon Aircraft Company: Docket No. 96-CE-34-AD.
Applicability: Models E33, F33, G33, E33A, F33A, E33C, F33C,
C35, D35, E35, F35, G35, H35, J35, K35, M35, N35, P35, S35, V35,

95, B95, B95A, D95A, and E95 Airplanes (all serial numbers),
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (g) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required within the next 50 hours time-in-service
(TIS) or at the door handle removal, whichever occurs first, after
the effective date of this AD, unless already accomplished.
To prevent unintentional opening of the interior cabin side door
and the interior utility door while in flight, which if not detected
and corrected, could result in injury to passengers or loss of
control of the airplane, accomplish the following:
(a) Check the interior side cabin door handle and the utility
door handle for correct locking operation of the handle in
accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon
Service Bulletin (SB) No. 2693, Issued May, 1996.
(b) The check required in paragraph (a) of this AD may be
performed by the owner/operator holding at least a private pilot
certificate as authorized by section 43.7 of the Federal Aviation
Regulations (14 CFR 43.7), and must be entered into the aircraft
records showing compliance with this AD in accordance with section
43.11 of the Federal Aviation Regulations (14 CFR 43.11).
(c) If the door handle is locked and will only unlock by
depressing the handle door lock release button, then no further
action is necessary.
(d) If the handle opens the door without depressing the handle's
lock release button, prior to further flight, correct the door lock
by removing the handle, and installing the handle so that the handle
lock release button locks the door in accordance with the
ACCOMPLISHMENT INSTRUCTIONS section in Raytheon SB No. 2693, Issued
May, 1996.
(e) The action required in paragraph
(d) of this AD must be accomplished by a licensed airframe
mechanic.
(f) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
(g) An alternative method of compliance or adjustment of the
compliance time that provides an equivalent level of safety may be
approved by the Manager, Wichita Aircraft Certification Office
Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas
67209. The request shall be forwarded through an appropriate FAA
Maintenance Inspector, who may add comments and then send it to the
Manager, Wichita Aircraft Certification Office.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Wichita Aircraft Certification Office.
(h) All persons affected by this directive may obtain copies of
the document referred to herein upon request to Raytheon Aircraft
Company, P.O. Box 85, Wichita, Kansas 67201-0085; or may examine
