Duncan Aviation to Perform NDT Inspection for Enstrom Helicopter Service Direct Bulletin

LINCOLN, NEB. — Duncan Aviation is geared up and prepared to perform the magnetic particle inspection required on the main rotor spindle of the Enstrom F-28A, F-28C, F-28F, 280, 280C, 280F and 280FX model helicopter.

In February, Enstrom Helicopter Corporation issued Service Directive Bulletin No. 0199 to address potential spindle separation due to fatigue. This affects all the serial numbers of the main rotor spindle, P/N 28-14282-11 and P/N 28-14282-13.

For compliance, spindles with 5,000 hours or more time-in-service need to be inspected within the next five hours time-in-service and repeated every 300 hours thereafter. Spindles with fewer than 5,000 hours time-in-service need to have this inspection performed at or before reaching this threshold.

Once Duncan Aviation receives the spindle, accessory technicians are able to turn the unit the same day. With enough advanced notice, Enstrom operators can expect to receive their spindle back the next day.
