Which aircraft AD 86-07-07 applies to

MakesBell Helicopter Textron
Part-conditional — 204-011-128-1, DW-6ZZ.

Applies to the main rotor pitch change link universal, Bell P/N 204-011-128-1; unless already accomplished, inspect the universal assembly within 15 days after the effective date for supplier P/N 'DW-6ZZ' (Arko Precision Machinists); if found, replace before further flight with a serviceable assembly; if the P/N is missing or cannot be seen, apply MIL-G-81322 grease to each of the two grease fittings on the universal.

Whether AD 86-07-07 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 86-07-07 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.
