61-14-06 SNOW: Amdt. 306 Part 507 Federal Register July 11, 1961. Applies to All Model S2A Aircraft (Restricted Category).

Initial compliance required within 25 hours' time in service after the effective date of this AD unless accomplished within 75 hours' time in service preceding such date. Subsequent compliance required at each 100 hours' time in service after the initial compliance date.

Due to reports of excessive cable wear occurring at two AN 210-3B pulleys in the aileron system aft of the hopper and two AN 210-3B pulleys in the elevator system on the left and right of the pilot seat, the following must be accomplished:

(a) Detach the aileron and elevator cables by disconnecting the turnbuckles to obtain slack at the two pulleys in each system. Visually inspect the cables for fraying by flexing the cable in the areas of pulley contact in accordance with Snow Service Letter No. 4. Replace all frayed cables prior to further flight.

(b) Inspection of the elevator cable may be discontinued when the two AN 210-3B elevator system pulleys to the left and right of the pilot seat are replaced with AN 210-4B pulleys, in accordance with Snow Service Letter No. 6. Inspection of the aileron cable may be discontinued when the aileron cable system is replaced with a push-pull tube system in accordance with Snow Service Letter No. 7.

(Snow Service Letters 4, 6, and 7 cover this subject.)
