Can the MORE Supplemental Type Certificate(s) (STC) be used by Federal Aviation Regulations (FAR) Part 135 or Part 121 operators?
Answer: The MORE STC(s) may be used by FAR 135 (or FAR 121, FAR 91 or FAR 137) operators. In 1994 FAA Flight Standards (Washington) issued Flight Standards Information Bulletin number FSAW 94-48 to explain to BOTH operators and FAA Principal Maintenance Inspectors, how the MORE STC(s) should be used by FAR 135 operators. While 94-48 is still helpful information, the FAA allowed 94-48 to expire on May 31, 2001. A copy of 94-48 will be provided upon request.
