Airworthiness Directives; The New Piper Aircraft, Inc. (formerly Piper Aircraft Corporation) PA-31 Series Airplanes

What this AD requires

This amendment supersedes Airworthiness Directive (AD) 80-26- 05, which currently requires you to repetitively inspect the main landing gear (MLG) inboard door hinges and attachment angles for cracks on certain The New Piper Aircraft, Inc. (Piper) PA-31 series airplanes. AD 80-26-05 also requires you to replace any cracked MLG inboard door hinge or attachment angle with parts of improved design. This AD results from the Federal Aviation Administration's policy on aging commuter-class aircraft and the determination that an improved design MLG inboard door hinge and attachment assembly, when incorporated, will eliminate the need for the currently required repetitive short-interval inspections; however, we have received reports of cracks in the improved design MLG inboard door hinge assemblies on the affected airplanes. This AD retains the current repetitive inspections contained in AD 80-26-05, and requires inspections on the improved design parts. The actions specified by this AD are intended to detect and correct cracked MLG inboard door hinge assemblies. These cracked door hinge assemblies could result in the MLG becoming jammed, with consequent 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.

Applies only to airplanes equipped with Piper P/N 46653-00 or 47529-32 aluminum main landing gear door hinge assemblies (or FAA-approved equivalent). Serial ranges by model: PA-31 and PA-31-300 S/N 31-2 through 31-900 and 31-7300901 through 31-8312019; PA-31-350 S/N 31-5001 through 31-5004 and 31-7305005 through 31-8553002; PA-31-325 S/N 31-7400990 and 31-7512001 through 31-8312019; PA-31P S/N 31P-1 through 31P-109 and 31P-7300110 through 31P-7730012; PA-31T S/N 31T-7400002 through 31T-8120104; PA-31T1 S/N 31T-7804001 through 31T-8104073, 31T-8104101, 31T-8304001 through 31T-8304003, and 31T-1104004 through 31T-1104017; PA-31T2 S/N 31T-8166001 through 31T-8166076 and 31T-1166001 through 31T-1166008; PA-31T3 S/N 31T-8275001 through 31T-8475001 and 31T-5575001; PA-31P-350 S/N 31P-8414001 through 31P-8414050. Model PA-31-310 aircraft are actually Model PA-31 airplanes and must also comply.

Whether AD 2000-25-01 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.
Is AD 2000-25-01 complied with on your aircraft?

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.
