Which aircraft AD 70-17-04 applies to

ModelsMS. 880B, MS. 885, MS. 894A, MS 880, MS 885, MS 894

Install flexible fuel lines between the engine pump and carburetor and in the fuel pressure system, per Parts 2 and 3 of SOCATA Service Bulletin No. 56, dated December 1968, or later SGAC-approved issue.

Whether AD 70-17-04 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 70-17-04 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.
