## The airworthiness directive

80-14-02 PIPER AIRCRAFT CORPORATION: Amendment 39-3819. Applies to Model PA-28-181, serial numbers 28-7790032 through 28-8090227; Model PA-32-300, serial numbers 32-7640001 through 32-7740032 and Model PA-32R-300, serial numbers 32R-7680001 through 32R-7780148 airplanes certificated in all categories.

Compliance required within the next 50 hours time in service after the effective date of this AD, unless already accomplished.

To prevent separation of the throttle control cable rod end from the throttle arm on the affected Models PA-28 and PA-32 airplanes, and rod end binding with possible subsequent throttle cable failure on the affected Model PA-28 airplanes, accomplished the following.

  (a) For the Model PA-32-300 and PA-32R-300 series airplanes, replace the throttle linkage connecting hardware in accordance with the instructions contained in Piper Service Bulletin No. 537, dated January 12, 1977.

  (b) For the Model PA-28-181 airplanes, modify the throttle linkage in accordance with the instructions listed in the "Throttle Linkage Modification Kit," Piper Part Number 764- 009V.

NOTE: Piper Service Bulletin No. 679 pertains to this subject.

  (c) Make an appropriate maintenance record entry.

An equivalent method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region.

This amendment is effective July 10, 1980.

## NTSB investigations that cite this AD (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB BFO94FA140](https://openairdocs.org/ntsb/BFO94FA140), Aug 19, 1994: Piper PA-32R-300 (N4316X), Roanoke, VA, destroyed, 2 fatal. Probable cause: THE DISCONNECTION OF THE THROTTLE CABLE FROM THE THROTTLE ARM ON THE FUEL INJECTOR SERVO.
