## The airworthiness directive

62-07-01 GENERAL DYNAMICS/CONVAIR: Amdt. 412 Part 507 Federal Register March 24, 1962. Applies to All Models 22 and 22M Aircraft.

Compliance required within the next 75 hours' time in service after the effective date of this AD and at periods thereafter not to exceed 75 hours' time in service.

To prevent further failures of the forward support trunnions for all elevator and rudder balance boards P/N 22-14715-7, 9, 15, and 17, the following shall be accomplished:

Inspect the forward support trunnions for all elevator and rudder balance boards P/N 22- 14715-7, 9, 15, and 17 for failure or cracking. The inspection shall be conducted in accordance with Part A(1) of General Dynamics/Convair Alert Service Bulletin 880-A27-55 or 880M-A27- 24. Replace any failed or cracked part prior to further flight.

When elevator balance board forward support trunnions, P/N 22-14715-15 and P/N 22- 14715-17, are replaced with Convair P/N's 22-11634-1 and 22-11634-3, respectively, or FAAapproved equivalents, the 75 hour repetitive inspections of the support trunnions for the elevator balance boards may be discontinued.

When rudder balance board forward support trunnions, P/N 22-14715-7 and P/N 22- 14715-9, are replaced with Convair P/N's 22-11634-5 and 22-11634-801, respectively, or FAA approved equivalents, the 75 hour repetitive inspections of the support trunnions for the rudder balance boards may be discontinued.

Upon request of the operator an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Western Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator. (Convair Alert Service Bulletins 880-A27-55A and 880M-27-24A cover this same subject.)

This directive effective upon publication in the Federal Register forall persons except those to whom it was made effective immediately by telegram dated March 9, 1962.

Revised April 7, 1962.
