Airworthiness Directives; Societe Nationale Industrielle Aerospatiale and Eurocopter France Model AS-355 E, F, F1, F2, and N Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Societe Nationale Industrielle Aerospatiale and Eurocopter France (Eurocopter France) Model AS-355 E, F, F1, F2, and N helicopters. This action requires a check to ensure that the main gearbox (MGB) oil pressure warning light illuminates during each shutdown of the helicopter engine until the MGB oil pressure switch (switch) is removed and replaced. This amendment is prompted by a malfunction of the MGB switch. This condition, if not corrected, could result in failure to detect a loss of oil pressure, loss of the MGB, loss of power to the main rotor system, and subsequent loss of control of the helicopter.

Part-conditional — 704A37-721-082, 704A37-721-089, 704A37-721-014.

Applicability provision referenced a preceding paragraph not fully captured; model family inferred from referenced Eurocopter Service Bulletin AS 355 No. 01.39, Revision 1 (dated April 21, 1994). AD requires replacing main gearbox (MGB) pressure switch P/N 704A37-721-082 (mod 350A07-7141) with P/N 704A37-721-089 (mod 350A07-7152) or Jaeger switch P/N 704A37-721-014.

Whether AD 95-12607 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 95-12607 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.
