RIN 2120-AA64
Airworthiness Directives; Piper Aircraft, Inc. PA-23, PA-31, and
PA-42 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Piper Aircraft, Inc. (Piper) PA-23 series airplanes and all PA-
31 and PA-42 series airplanes. This proposed AD would establish life
limits for safety-critical nose baggage door components. This proposed
AD would also require you to replace those safety-critical nose baggage
door components and repetitively inspect and lubricate the nose baggage
door latching mechanism and lock assembly. This proposed AD results
from several incidents and accidents, including fatal accidents, where
the nose baggage door opening in flight was listed as a causal factor.
We are proposing this AD to detect and correct worn, corroded, or non-
conforming nose baggage door components, which could result in the nose
baggage door opening in flight. 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.
DATES: We must receive comments on this proposed AD by May 11, 2009.
ADDRESSES: Use one of the following addresses to comment on this
proposed AD:

Discussion
On January 5, 2008, a Piper PA-31-350 airplane crashed shortly
after takeoff. The National Transportation Safety Board preliminary
report of the fatal accident indicates the nose baggage door opened in
flight. Our investigation of the accident indicates the nose baggage
door opening in flight was a causal factor in the accident. The
investigation also indicated that the baggage door did not conform to
the type design and was not in a condition for safe operation. We have
also received several other incident and accident reports where the
nose baggage door opening in flight was listed as a causal factor.
Our investigation of PA-31 airplanes has found additional
nonconforming nose baggage door components. Examples of problems
discovered are: key locks that have been replaced with locks that allow
the key to be removed when the door is unlocked; bent, corroded, worn,
or broken parts; parts installed backwards; inoperative warning
systems; and installation of secondary latches that are not strong
enough to secure the door in a closed position.
This condition, if not corrected, could result in the nose baggage
door opening in flight. 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.
Relevant Service Information
We have reviewed Piper Aircraft, Inc. Service Bulletin No. 1194A,
dated November 10, 2008.
The service information describes procedures for:
Repetitive inspection of the nose baggage door latching
mechanism and lock assembly and replacement of life limited parts as
identified in the service bulletin; and
Repetitive lubrication and inspection of the nose baggage
door latching and locking components.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would require you to replace safety-critical nose baggage door
components and repetitively inspect and lubricate the nose baggage door
latching mechanism and lock assembly. This proposed AD would also
establish life limits for
[[Page 10196]]
safety-critical nose baggage door components.
Differences Between This Proposed AD and the Service Information
The applicability of this AD is expanded to include Models PA-23,
PA-23-160, and PA-23-235 airplanes that have a nose baggage door
installed. These models were not manufactured with a nose baggage door
and are not included in Piper Aircraft, Inc. Service Bulletin No.
1194A, dated November 10, 2008. However there are PA-23, PA-23-160, and
PA-23-235 airplanes in service that may have been modified with the
applicable nose baggage door installed. The requirements of this
proposed AD, if adopted as a final rule, would take precedence over the
provisions in the service information.
Costs of Compliance
We estimate that this proposed AD would affect 8,000 airplanes in
the U.S. registry.
We estimate the following costs to do the proposed inspection and
parts replacement:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $80 per hour = $320........................... $190 $510 $4,080,000
----------------------------------------------------------------------------------------------------------------
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
regulation:
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. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at http://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Piper Aircraft, Inc.: Docket No. FAA-2009-0218; Directorate
Identifier 2009-CE-006-AD.
