Abstract : Evaluation of the altimeter installed in a TF-9J commenced on 14 November 1963. After a total of 7.6 project hours, the plane was put in major check, during which foreign object damage to the engine was discovered. On 17 December 1963 the hydraulic pressure line was inadvertently coupled with the static system line at the airplane tail quick disconnect. As a result of this maintenance error, hydraulic fluid flowed into the pitotstatic instruments during turnup. The altimeter case was approximately half filled with hydraulic fluid indicating aneroid rupture and possibly additional damage. (Author)
