Compliance required as indicated. Warren McArthur end fittings, P/N 275-AS26 (Air Associates P/N M-1842) have been found to be of insufficient strength for use in two-person belts. These fittings are not marked, have a fitting plate thickness of 1/8 inch, and may be identified by comparison with Figure 1. One-person belts using these fittings must be modified not later than the next annual inspection (or the next seat overhaul for aircraft on a continued maintenance basis) so that the label will read "APPROVED FOR ONE PERSON". This may be done by blanking out the words "OR TWO" and the letter "S" in the word "PERSONS" on the label with India ink or an equally effective method. All such belts presently used in two-person applications shall be removed and replaced by other belts approved for two persons not later than May 1, 1950. Care should be taken not to confuse these fittings with another Warren McArthur fitting P/N 13971 (also known as P/N 314-AS12) which is identical in appearance except that the fitting plate thickness is 5/32 inch. This supersedes AD 50-02-01. FOOTER:
