Airworthiness Directives; Piper Aircraft, Inc. (Type Certificate Previously Held by The New Piper Aircraft Inc.) Airplanes
Notice Of Proposed Rulemaking (Nprm).
We propose to supersede an existing airworthiness directive (AD) that applies to certain Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA-31T and PA-31T1 airplanes. The existing AD currently requires correcting a model identification error on the aircraft data plate. Since we issued that AD, we have become aware that some owner/operators of the affected airplanes modified the aircraft data plate in error because of confusion in the serial number applicability. Because of the confusion, the manufacturer has issued new service information to clarify affected airplane serial numbers. This proposed AD would require determining the airplane model based on the serial number and modifying the aircraft data plate to properly identify the airplane model. This proposed AD would also require doing a detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked data plate and take necessary corrective actions based on the search findings. We are proposing this AD to correct the unsafe condition on these products.

Discussion Back to Top
On May 27, 1980, AD 80-11-06, amendment 39-3776 (45 FR 35309), was published in the Federal Register for certain Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA-31T and PA-31T1 airplanes. That AD requires correcting a model identification error on the aircraft data plate. Certain Model PA-31T airplanes have been improperly identified as a Model PA-31T1 airplane on the aircraft data plate.
Actions Since Existing AD Was Issued Back to Top
Since we issued AD 80-11-06 (45 FR 35309, May 27, 1980), we have become aware that the aircraft data plate on some of the affected airplanes have been modified in error because of confusion in the serial number applicability.
The requirements in AD 80-11-06 (45 FR 35309, May 27, 1980), match those in Piper Service Bulletin 670, issued December 3, 1979. Also, the type certificate data sheet (TCDS) did not clearly distinguish the serial numbers for the Models PA-31T and PA-31T1 airplanes.
As a result of the confusion, Piper Aircraft, Inc. has issued a new service bulletin to clarify the affected serial numbers. We are also working with Piper Aircraft, Inc. to clarify the serial numbers in the TCDS.
Relevant Service Information Back to Top
We reviewed Piper Aircraft Inc. Mandatory Service Bulletin No. 1235, dated November 3, 2011. The service bulletin describes procedures for determining the airplane model based on the serial number and provides instructions for modifying the aircraft data plate to properly identify the airplane model.
FAA's Determination Back to Top
We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
Proposed AD Requirements Back to Top
This proposed AD would retain all requirements of AD 80-11-06 (45 FR 35309, May 27, 1980). This proposed AD would clarify the serial number applicability of the affected model airplanes. This proposed AD would also require a detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked aircraft data plate and take necessary corrective actions.
Costs of Compliance Back to Top
We estimate that this proposed AD affects 158 airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Inspect the aircraft data plate||1 work-hour × $85 per hour = $85||Not applicable||$85||$13,430|
We estimate the following costs to do any necessary modification and/or records search that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need modification:
|Action||Labor cost||Parts cost||Cost per product|
|Modify the aircraft data plate||1 work-hour × $85 per hour = $85||Not applicable||$85|
|Detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked aircraft data plate||4 work-hours × $85 per hour = $340||Not applicable||340|
Authority for This Rulemaking Back to Top
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 Back to Top
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),
(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.
The Proposed Amendment Back to Top
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 Back to Top
1. The authority citation for part 39 continues to read as follows:
§ 39.13 [Amended]
2. The FAA amends § 39.13 by removing airworthiness directive (AD) 80-11-06, Amendment 39-3776 (45 FR 35309, May27, 1980), and adding the following new AD:
Piper Aircraft, Inc. (Type Certificate previously held by The New Piper Aircraft Inc.): Docket No. FAA-2012-0251; Directorate Identifier 2012-CE-002-AD.
(a) Comments Due Date Back to Top
The FAA must receive comments on this AD action by April 23, 2012.
(b) Affected ADs Back to Top
This AD supersedes AD 80-11-06, Amendment 39-3776 (45 FR 35309, May 27, 1980).

(d) Subject Back to Top
Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 1100, Placards and Markings.
(e) Unsafe Condition Back to Top
This AD was prompted by reports that some owner/operators of the affected airplanes modified the aircraft data plate in error because of confusion in the serial number applicability. We are issuing this AD to correct the unsafe condition on these products.
(f) Compliance Back to Top
Comply with this AD within the compliance times specified, unless already done.
(g) Inspect the Aircraft Data Plate Back to Top
Within the next 100 hours after the effective date of this AD, inspect the markings on the aircraft data plate. Do the inspection following Part I of Piper Aircraft, Inc. Mandatory Service Bulletin No. 1235, dated November 3, 2011.
(1) If the aircraft data plate is correctly marked, make a logbook entry showing compliance with this AD, and no further action is required.
(2) If the aircraft data plate is incorrectly marked, continue with paragraphs (h) and (i) of this AD.
(h) Modify the Aircraft Data Plate Back to Top
Before further flight after the inspection required in paragraph (g) of this AD, modify the aircraft data plate following Part II of Piper Aircraft, Inc. Mandatory Service Bulletin No. 1235, dated November 3, 2011.
(i) Detailed Aircraft Records Search Back to Top
Before further flight after the modification required in paragraph (h) of this AD:
(1) Do a detailed search of the aircraft maintenance records and documents to include, but not limited to, ADs, special airworthiness information bulletins (SAIBs), service bulletins (SBs), and other service documents; installed supplemental type certificates (STCs) and parts manufacturing approval (PMAs); and instructions for continued airworthiness (ICAs). Each document found must be assessed to ensure proper actions have been made to maintain airworthiness as affected by the model number of the aircraft. Part 135 operators and other operators utilizing FAA-approved maintenance programs will need to address changes to their inspection programs and related documents.
Although some of the above documents may not be mandatory for compliance, it is still necessary to evaluate them to ensure that any voluntary compliance does not negatively affect the airworthiness of the airplane.
(2) Identify all discrepant conditions for misidentified aircraft and coordinate with the geographic Flight Standards District Office (FSDO) and the Atlanta Aircraft Certification Office (ACO) to determine necessary corrective actions. Also, coordinate with the geographic FSDO to arrange for revisions to the airworthiness certificate, registration, and other potential document/certificate revisions. The following is a list of example discrepant conditions that may be found during the records search:
(i) An AD was complied with that was applicable to the incorrect model, but not applicable to the corrected model.
(ii) A required AD for the corrected model was not complied with.
(iii) A maintenance action was performed that was recommended, but not mandatory, for the incorrect model, but not applicable to the corrected model.
(iv) A PMA part was installed that was applicable for the incorrect model, but not for the corrected model.
(v) An STC was installed that was applicable for the incorrect model, but not for the corrected model.
(vi) An STC was installed that was applicable for both the incorrect and corrected model, but all related, applicable ADs for the corrected model were not complied with.
(j) Alternative Methods of Compliance (AMOCs) Back to Top
(1) The Manager, Atlanta ACO, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO, send it to the attention of the person identified in the Related Information section of this AD.
(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
(3) AMOCs approved for AD 80-11-06 (45 FR 35309, May 27, 1980), are approved as AMOCs for this AD.
