What this AD requires

This amendment revises Airworthiness Directive (AD) 96-10-01, which currently requires a complete landing light support replacement on certain The New Piper Aircraft, Inc. (Piper) Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 airplanes. Some of the serial numbers for these airplanes were incorrectly referenced in the Applicability section of AD 96-10-01. This AD maintains the requirements of AD 96-10-01, and corrects the serial numbers referenced in the Applicability section. The actions specified by this AD are intended to prevent the landing light retainer support seal from being ingested by the updraft carburetor, which could result in rough engine operation or possible engine failure and loss of control of the airplane.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
