Within the next 50 hours' time in service after the effective date of this AD and thereafter at intervals whenever the gear box oil contents are checked, inspect the oil metering unit and bearing cover plate for security, i.e., nuts are tight and spring washers fully compressed. Secure as necessary.

(b) For all the applicable airplanes -

At the next overhaul of the Supercharger or within the next 1500 hours' time in service, whichever occurs earlier, after the effective date of this AD, replace and lockwire the oil metering unit and bearing cover retaining nuts, in accordance with Godfrey Precision Products, Ltd. Service Bulletin No. 21-116-1195, Revision 2, dated February 1, 1968, or later ARB - approved revision or an equivalent approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Region.

This amendment becomes effective November 21, 1968.
