Airworthiness Directives; Piper Aircraft, Inc. Airplanes


AGENCY:
 
Federal Aviation Administration (FAA), DOT.


ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
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.


DATES:
 
This AD is effective November 3, 2011.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in this AD as of July 24, 2009 (74 FR 29118, June 19, 2009).

SUPPLEMENTARY INFORMATION:


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 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 commented that


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.''
