Is AD 97-01-01 a recurring Airworthiness Directive?

Yes — AD 97-01-01 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directive 97-01-01

Q: Which aircraft does AD 97-01-01 apply to?

AD 97-01-01 applies to Piper Aircraft Corporation — models PA24, PA24-250, PA24-260, PA24-400, PA30, PA39, PA28R-180, PA28R-200. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; The New Piper Aircraft, Inc. PA24, PA28R, PA30, PA32R, PA34, and PA39 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that supersedes AD 95-20-07, which currently requires repetitively inspecting the main gear sidebrace studs for cracks on certain The New Piper Aircraft, Inc. (Piper) PA24, PA28R, PA30, PA32R, PA34, and PA39 series airplanes, and replacing any cracked main gear sidebrace stud. This AD retains the repetitive inspection and possible replacement requirements of AD 95-20-07; specifies in the ``Applicability'' section of the AD that certain Model PA34-200T airplanes could contain a certain main gear sidebrace assembly configuration that is not affected; and incorporates additional modification and replacement options. This AD results from additional information received by the Federal Aviation Administration (FAA) after the issuance of AD 95-20-07 on the design and service history of the affected airplanes concerning this subject. The actions specified by this AD are intended to prevent a main landing gear collapse caused by main gear sidebrace stud cracks, which could result in loss of control of the airplane during landing operations.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 20829-00, 22512-00.

Main gear sidebrace stud crack inspection (fluorescent/magnetic particle) to prevent MLG collapse. Compliance interval differs by model group: PA28R-180/-200/-201/-201T, PA32R-300, PA34-200/-200T within 100 hrs TIS after effective date (or 500 hrs TIS after a prior inspection/replacement); PA24/PA24-250/-260/-400, PA30, PA39 within 100 hrs TIS after effective date (or 1,000 hrs TIS after a prior inspection/replacement). Original factory-installed stud P/N was 20829-00 on PA24 and PA24-250, and 22512-00 on PA24-260, PA24-400, PA30, and PA39. Any cracked stud must be replaced prior to further flight.

Whether AD 97-01-01 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

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.
