Part-conditional — SB1138-101.

Bearings manufactured by MRC not identified with a white dot on the grease fitting or a serial number, with under 100 hours operating time, to be removed. Replace with MRC P/N SB1138-101 bearings identified with a white dot and/or serial number, or with the alternate bearing manufactured by Fafnir approved for this installation. Compliance per Alert Service Bulletin (ASB) 76-66-20, paragraph E.1, dated July 25, 1985. Host aircraft/rotorcraft type not stated in available text.

Whether AD 85-15-06 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 85-15-06 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.
