REGULATORY TEXT:  
58-10-07 VICKERS: Applies to All Viscount 700 Series Aircraft.

Compliance required as indicated.

Cases have been reported of a variation in the clearances between the aileron lock arms and their associated locking levers on different aircraft when the control locks are disengaged. Vickers-Armstrong has issued the following corrective measures which the British Air registration Board considers mandatory:

1. As soon as possible, but not later than August 1, 1958, all aircraft should be inspected to determine that a nominal clearance of 0.15 inch is provided at the inboard and outboard aileron control lock assemblies.

2. If the clearances are less than 0.10 inch, the locking levers can be filed to a maximum of 0.10 inch to obtain the required clearance of not less than 0.15 inch.

3. If the clearances are between 0.10 and 0.15 inch, the filing of the locking levers to obtain the required clearance of not less than 0.15 inch, can be deferred until the next major check or next removal of the ailerons, whichever occurs sooner.

The FAA concurs with this action and considers compliance therewith mandatory.

(Vickers-Armstrong PTL No. 173 and Modification No. D.2491 cover this subject.)
