Airworthiness Directives; Eurocopter France Model SA. 315B Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA. 315B helicopters. This action requires inspecting the spar skin and main rotor blade (blade) root reinforcement strip area for bonding separation, corrosion, or a crack, and replacing the blade, if necessary. This amendment is prompted by the in-flight failure of a blade. The actions specified in this AD are intended to detect bonding separation, corrosion, or a crack in the area of the blade root reinforcement strip, which could result in failure of the blade and subsequent loss of control of the helicopter.

Which aircraft AD 99-07-08 applies to

ModelsSA-315

Main rotor blade spar-skin / root-reinforcement-strip bonding-separation, corrosion, or crack inspection AD; actions per Eurocopter SA 315 Service Bulletin No. 05.34, Revision No. 1, dated September 28, 1998.

Whether AD 99-07-08 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 99-07-08 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.
