80-21-05 BELL: Amendment 39-3931. Applies to Model 205A-1 and 212 helicopters equipped with fixed float landing gears. (Airworthiness Docket No. 76-SW-28)
Compliance required within 50 hours' time in service after the effective date of this Ad unless already accomplished.
To preclude possible fatigue cracks from occurring in the landing gear cross tubes under the riveted saddle fittings, install forward and aft cross tube assemblies, P/N 205-050-114-23 and -25 respectively or higher dash numbers that have clamp-on saddle fittings.
Float kit installation, P/N 205-706-050-101, uses cross tubes having clamp-on saddle fittings.
(Bell Helicopter Textron Alert Service Bulletin Nos. 212-80-18 and 205-80-13 also pertain to this subject.)
This amendment becomes effective October 15, 1980.
