Flight manual should be in the zipped pouch behind the pilot’s headrest in the aircraft. Also very important to find the maintenance logbooks to check the weight and balance condition. The ship had repairs some years ago and became somewhat tail-heavy. Some of our lighter pilots will need a shot bag or parachute to bulk up since it doesn’t accept conventional ballast. Those books should be in the office but very, very important to find and check them. Know thy CG.
