REGULATORY TEXT:  
61-14-03 CONVAIR: Amdt. 301 Part 507 Federal Register July 7, 1961. Applies to All Model 22 (880) Aircraft Having Cartridge Assembly-Rudder Spring P/N 22-46223 Installed.

Compliance required as indicated.

One instance has occurred on the Model 22 (880) aircraft in which the cartridge assembly-rudder spring P/N 22-46223 seized due to corrosion and galling, resulting in limited rudder travel. The effects of this malfunction upon operational safety are such as to require accomplishment of the following:

(a) Within the next 100 hours' time in service unless already accomplished in the last 220 hours' time in service, and at each 320 hours' time in service thereafter, conduct the following operational check: Lock the rudder flight tab and rudder in neutral position and operate the rudder pedals right and left until the cockpit stops are contacted 5 or more times. If any roughness in operation is noted, remove cartridge assembly-rudder spring P/N 22-46223, and replace with a P/N 22-46223 which has been inspected and found free of corrosion or galling and operationally checked, or a part reworked in accordance with the provisions of Convair Service Bulletin No. 27-33 and reidentified as P/N 22-46223-1, prior to further flight.

(b) When the cartridge assembly-rudder spring is replaced with an assembly reworked in accordance with provisions of Convair Service Bulletin 27-33 and reidentified as P/N 22-46223-1, the inspection specified in (a) may be discontinued.

(Convair Service Bulletin No. 27-33 covers this same subject.)

This directive effective July 7, 1961.
