Notified 0935 local by Lenawee County Airport manager that there was an aircraft accident. He stated that is a single engine Mooney and the pilot was not hurt.

The aircraft was facing northeast on the west side of the runway opposite the direction of impact. It appeared that the aircraft landed hard approximately 450 feet short of the runway threshold in the grass skidded across asphalt threshold and into the grass left of the runway for another 450 feet.

The aircraft was mostly intact except for both main landing gear and doors were sheared off. The initial damage assessment that the aircraft was severely damaged and would be considered an accident.

The major damage was as follows:

Both main gear and doors were sheared off.

Nose gear collapsed into wheel well.

Propeller blades bent back.

Empennage bent back, horizontal bent and fuselage twisted at empennage attach points.

Left wing bent at outboard wing.

All wing flight surfaces damaged.

Initial preliminary aircraft flight control assessment was as follows:

Tail stabilator position was full down

Pitch trim was 2 wheel notches from nose full up (manual pitch trim setting)

Pitch trim continuity was verified, however trim travel was limited to full nose up to neutral. Tail damage limited travel.

Pitch electric trim was operative and indication verified on garmin MFD display, however trim travel was limited to full nose up to neutral. Tail damage limited travel.

Elevator control continuity was verified; however control travel was not verified due to tail damage.

Yaw control continuity was verified and control travel was not verified.

Rudder electric trim was verified as operative, roll control continuity was verified; however control travel was not verified due to wing and aileron damage. Speed brakes did deploy and retracted when operated.

Other notes:

Landing gear handle was in the down position, flaps were up, garmin flight displays did power up and appeared to operate.

No burnt smell apparent from displays.

Interior items spread about the cabin and loose.

The following items were in the front cockpit seats:

Back up oxygen bottle and mask

2 Oxygen masks with boom mikes

CO2 detector

Blood oxygen monitor.

2 Headsets

Pilot stated that en route he experienced a un commanded full up climb. He stated that he was cruise climbing at or about FL19 to FL25 at or about 750 per minute using auto pilot when event occurred.

He stated that it took all his might to push the yoke forward to keep from stalling the aircraft.

I asked if any inputs from the pitch trim had any effect, he stated no, the electric trim did not have any effect and he did not try the manual pitch trim.

He stated that he could not control pitch and wanted to keep from spinning the aircraft, had full power available and all other flight controls responded. He stated that he landed faster than normal to keep from stalling, but landed very hard and collapsed the gear.

I asked him if he anything else to add and could he write a statement. He said that he was pretty worked up and writes a statement later but added the following.

He also stated that he saw a ?wisp? Of smoke near the left MFD. I asked him if he could provide more detail about that he said he could not.

I asked him about oxygen usage. He stated he had a problem with his one back up bottle mask so he had to change to the airplane oxygen system but that was 45 minutes before the incident happened.
