AD 2009-13-06 R1

We are revising an existing airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-23, PA-23-160, PA-23-235, PA-23- 250, PA-23-250 (Navy UO-1), PA-E23-250, PA-31, PA-31-300, PA-31-325, PA-31-350, PA-31P, PA-31P-350, PA-31T, PA-31T1, PA-31T2, PA-31T3, PA- 42, PA-42-720, and PA-42-1000 airplanes that are equipped with a baggage door in the fuselage nose section (a nose baggage door). That AD currently establishes life limits and replacement requirements for safety-critical nose baggage door components and repetitive inspections and lubrication of the nose baggage door latching mechanism and lock assembly. This new AD removes the requirement for the nose baggage door compartment interior light inspection and retains the other requirements from AD 2009-13-06, Amendment 39-15944. This AD was prompted by further investigation and a request for an alternative method of compliance (AMOC). We are issuing this AD to correct the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by removing airworthiness directive AD 2009-13-06, amendment 39-15944 (74 FR 29118, June 19, 2009), and adding the following new AD:

2009-13-06 R1 Piper Aircraft, Inc.: Amendment 39-16820; Docket No. FAA-2009-0218; Directorate Identifier 2009-CE-006-AD.

(a) Effective Date

This airworthiness directive (AD) is effective November 3, 2011.

(b) Affected ADs

This AD revises AD 2009-13-06, amendment 39-15944 (74 FR 29118, June 19, 2009).

(c) Applicability

This AD applies to Models PA-23, PA-23-160, PA-23-235, PA-23- 250, PA-23-250 (Navy UO-1), PA-E23-250, PA-31, PA-31-300, PA-31-325, PA-31-350, PA-31P, PA-31P-350, PA-31T, PA-31T1, PA-31T2, PA-

[[Page 60369]]

31T3, PA-42, PA-42-720, and PA-42-1000 airplanes, all serial numbers, that are:
(1) Certificated in any category; and
(2) Equipped with a baggage door in the fuselage nose section (a nose baggage door).

(d) Subject

Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code, 52, Doors.

(e) Unsafe Condition

This AD was prompted by several incidents and accidents, including fatal accidents, where the nose baggage door opening in flight was listed as a causal factor. We are issuing this AD to establish life limits for safety-critical nose baggage door components, replace those safety-critical nose baggage door components, and repetitively inspect and lubricate the nose baggage door latching mechanism and lock assembly. The door opening in flight could significantly affect the handling and performance of the aircraft. It could also allow baggage to be ejected from the nose baggage compartment and strike the propeller. This failure could lead to loss of control.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 2009-13-06, amendment 39-15944 (74 FR 29118, June 19, 2009). That AD applies to the specified products. The NPRM published in the Federal Register on May 20, 2011 (76 FR 29176). That NPRM proposed to continue to require establishment of life limits for safety-critical nose baggage door components. That NPRM also proposed to continue to require replacement of those safety-critical nose baggage door components

[[Page 60368]]

and repetitive inspections and lubrications of the nose baggage door latching mechanism and lock assembly. The NPRM also proposed to remove the requirement for the nose baggage door compartment interior light inspection.

Comments

We gave the public the opportunity to participate in developing this AD. Ed Keith of Wright Air Service, the Aircraft Owners and Pilots Association, Gary King, and several others commentedthat they support the NPRM. The following presents a comment received on the proposal and the FAA's response to the comment:

Revised Compliance Time

Ben Stevens and another commenter requested we revise the compliance time in paragraph (f)(2) for the repetitive interval to allow for a 10 percent (110 hours) overrun for return to a maintenance base for inspection. The commenters stated this would match program extensions for aircraft that are in for-hire or instructional usage per 14 CFR 91.409(b) and that similar allowance had been allowed in other ADs.
We agree with this comment because the requested extension provides an acceptable level of safety for this class of aircraft. We revised paragraph (f)(2) of this AD to include the following text: ``Initially within 100 hours TIS after July 24, 2009 (the effective date retained from AD 2009-13-06, amendment 39-15944 (74 FR 29118, June 19, 2009); and repetitively thereafter at intervals of 100 hours TIS. The 100-hour interval may be exceeded by not more than 10 hours TIS to reach a place where the inspection can be done, per 14 CFR 91.409(b). The excess time used to reach a place where the inspection can be done must be included in computing the next 100 hours of TIS.''

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously and minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.

Costs of Compliance

We estimate that this AD affects 8,000 airplanes of U.S. registry.
We estimate the following costs to comply withthis AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection and parts replacement of 4 work-hours x $85 per hour $190 $530 $4,240,000
nose baggage door. = $340. ----------------------------------------------------------------------------------------------------------------

The new requirements of this AD add no additional economic burden. The increased estimated cost of this AD is due to increased labor cost from 2009 when AD 2009-13-06, amendment 39-15944 (74 FR 29118, June 19, 2009) was issued.

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 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 nationalgovernment 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 this AD:
(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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
