ABSTRACT:
An inspection access feature suitable for use in an inspection aperture in the casing of a gas turbine engine. The feature comprises a body portion which locates in the aperture and a removable plug portion which locates in an aperture extending through the body portion. The plug portion prevents the leakage of gases from a gas passage within the casing. If the plug portion is inadvertently not fitted, gas leakage from the casing is prevented by a pivoted flap which pivots to block the aperture through the body portion.
