Summary

This document clarifies information in Airworthiness Directive (AD) 85-02-05, which applies to all The New Piper Aircraft, Inc. (Piper) PA-20, PA-22, PA-23, PA-24, PA-25, PA-30, PA-31P, PA-36, PA-39, and PA-44 series airplanes. AD 85-02-05 currently requires installing on the pilot s instrument panel a Piper part number (P/N) 81090-02 placard, which provides information for operation of the parking brake. Piper has superseded that placard with a P/N 683-107 placard, and operators in need of a new placard can only obtain the P/N 683-107 placard. In this scenario, the owners/operators of the affected airplanes could not comply with AD 85-02-05 as currently written. The P/N 683-107 placard contains the same wording as the P/N 81090-02 placard. The actions specified in that AD are intended to prevent airplane controllability problems while involved in ground operation because of improper brake operations. This document maintains the placard requirement of AD 85-02-05, and adds the installation of the P/N 683-107 placard as an option of compliance.

Supplementary information

Discussion AD 85-02-05, Amendment 39-4984, currently requires the following on Piper PA-20, PA-22, PA-23, PA-24, PA-25, PA-30, PA-31P, PA-36, PA-39, and PA-44 series airplanes: installing on the pilot s instrument panel a Piper part number (P/N) 81090-02 placard, which provides information for operation of the parking brake. The actions required by AD 85-02-05 are intended to prevent airplane controllability problems while involved in ground operation because of improper brake operations.

Need for the Correction Piper has superseded the P/N 81090-02 placard with a P/N 683-107 placard, and owners/operators in need of a new placard can only obtain the P/N 683-107 placard. In this scenario, the owners/operators of the affected airplanes could not comply with AD 85-02-05 as currently written. The P/N 683-107 placard contains the same wording as the P/N 81090-02 placard.

Correction of Publication This document maintains the placard requirement of AD 85-02-05, adds the installation of the Piper P/N 683-107 placard as an option of compliance, adds a paragraph that allows the pilot to install the placard, adds the standard alternative method of compliance paragraph, and adds the AD as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).

Since this action only adds the Piper P/N 683-107 placard as an option of compliance, it has no adverse economic impact and imposes no additional burden on any person than would have been necessary to comply with AD 85-02-05. Therefore, the FAA has determined that prior notice and opportunity for public comment are unnecessary.

Adoption of the Correction Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
