What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Departed trl for flight to gladewater. Climbed to 3000' AGL. Approx. 2 mins in engine began to shake. Engine MFD showed normal. Approx. 2 mins later #5 cyl spiked red on temp. Manifold press went to 28.5 (was previously adjusted for Colorado 37.5). ATC stated divert to longview but trouble maintaining altitude. Engine smoothed out and gained 200'ALTITUDE. Contacted ggg for diversion however engine problem returned. Declared emer to divert to tyl, losing altitude. Informed ATC would pull chute if got below 1000'.in clouds at 1450' still losing altitude. Broke clouds at 1200' with stall warning. Observed field off to right. Selected high boost with no help. Pulled chute which completed deployment approx. 650'. Pilot reported the harness did not catch and pilot was knocked unconscious. Aircraft hit hard nose down to the left, breaking off LH wing. Passenger pulled pilot from aircraft. Gusty winds inflated chute and drug aircraft into treeline approx. 1/4 mile distant. Pilot reported oil pressure dropped during sequence, temp spiked.
Pilot suffered broken foot, concussion and bad sprains
2020-02-05 Onsite iic found no oil indicated on dipstick. Ac belt missing and cut in oil line directly below ac drive pulley. Ac accessory drive shaft bearing gone. Review of mx records show shaft removed by mx shop due to failure and no parts available at that time.
Examination of aircraft performed at asod with NTSB, Continental and Cirrus reps. Borescope of internal on cylinders found evidence of detonation on cylinders 1&3 with spark plug damage. Cylinder 5 also has a cracked piston with a missing land which exposes the top piston ring. Did manage to train approx. 3 qts of oil from sump.
Subsequent pressure test of oil line negative.
