Is AD 06-5009 a recurring Airworthiness Directive?

No — AD 06-5009 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 06-5009 apply to?

AD 06-5009 applies to Eurocopter — models AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Eurocopter France Model AS355E, F, F1, F2, and N Helicopters

What this AD requires

This amendment revises an existing airworthiness directive (AD) for Eurocopter France (ECF) Model AS355E, F, F1, F2, and N helicopters that currently requires certain checks of the magnetic chip detector plug (chip detector) and the main gearbox (MGB) oil-sight glass, certain inspections of the lubrication pump (pump), and replacing the MGB and the pump with an airworthy MGB and pump, if necessary. Also, the AD requires that before an MGB or pump with any hours time- in-service (TIS) can be installed, it must meet the AD requirements. This amendment retains those requirements but limits the applicability to one part number with certain serial-numbered pumps or modified after a certain date. This amendment is prompted by an investigation by the manufacturer that revealed a malfunction occurred after modifying the pump case on certain pumps after major overhaul and repairs. The actions specified by this AD are intended to limit the applicability to certain pumps, to detect sludge on the chip detector, to prevent failure of the MGB pump, seizure of the MGB, loss of drive to an engine and main rotor, and subsequent loss of control of the helicopter.

Part-conditional — 355A32-0700-01.

Applies only to helicopters with a main gearbox (MGB) lubrication pump P/N 355A32-0700-01, with a serial number (S/N) 5731 or higher, or with a S/N below 5731 if the pump has been overhauled or repaired after June 1, 1995. Certificated in any category.

Whether AD 06-5009 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 06-5009 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.
