Airworthiness Directives; Bell Helicopter Textron Canada (Bell) Model 427 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Bell model helicopters that requires replacing the hydraulic solenoid tee fitting (tee fitting) and tubes. This amendment is prompted by the manufacturer's discovery that tee fittings may be installed improperly and restrict hydraulic fluid flow. The actions specified by this AD are intended to prevent restricted flow of hydraulic fluid to the flight control hydraulic actuators resulting in loss of hydraulic control, excessive stiffness in the flight controls, and a subsequent forced landing of the helicopter.

Part-conditional — AS1003W060404, 427-080-058-101, 427-080-003-101, AS5230W0606, NAS1763W060404, 427-080-069-101, 427-080-068-101.

Model identified via the part-number/ASB prefix 427 (Bell 427); explicit 'Model 427' text not present in the extracted excerpt. Replace hydraulic solenoid tee fitting P/N AS1003W060404 and tubes P/N 427-080-058-101/-003-101 with union P/N AS5230W0606, tee fitting P/N NAS1763W060404, and tubes P/N 427-080-069-101/-068-101 per BHT ASB 427-01-02 dated 8/20/2001; required at next hydraulic filter/fluid replacement or within 30 days.

Whether AD 2003-04-14 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 2003-04-14 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.
