  • Methods and apparatus for maintaining alignment of borescope plungers
    Patent number: 6468033
    Abstract: A gas turbine engine borescope plug including a retainer that facilitates extending the useful life of the borescope plug is described. The borescope plug seals a pair of opposing inspection port openings in at least two respective spaced-apart walls and maintains sealing contact despite differential thermal growth between the two walls. The borescope plug includes the retainer, a plunger, and a biasing mechanism. The plunger extends through the biasing mechanism and the retainer. The retainer contacts the cylindrical biasing mechanism and maintains its position relative to the plunger to prevent contact between the plunger and the biasing mechanism.
