Loving these stories!
For me:
Also the battery on the Phantom.
Ramp actuator on the Phantom.
Stabilator feel bellows on the Phantom. (Not a regular thing to change but it did involve hanging through the access panel upside down for many hours working with a torch and mirror.)
Anything in Zone 19 on the Tornado - especially in hotter climates.
I haven't resorted to superglue on my fingers to hold washers in place but - look away now if you are of a nervous disposition - I have deliberately jammed split pin legs under my nail and then put my arm back in the access hole to reach a very inaccessible bolt. Makes me sick to recall it!
Keep 'em coming!
