Requirement: Action in accordance with Mandatory British Aerospace SB 52-JM 7752. Compliance: At the next scheduled 600 hour maintenance check after 6 March 1992 or by 6 July

1992; whichever occurs first.

Background: During a scheduled inspection on an in-service aircraft, an escape hatch could not be removed without damaging the ceiling trim, due to interference between the shear fitting on the hatch and a furnishing ceiling panel. This interference can prevent removal of the escape hatch in an emergency. The compliance date required by the UK CAA is extended by two months.
