NTSB narrative
THE ACFT COLLIDED WITH A POWER LINE AND NOSED OVER DURING AN ATTEMPT TO RECOVER FROM A SIMULATED FORCED LANDING. THE CFIREPORTEDLY 'CLEARED' THE ENGINE DURING THE APPROACH BUT WHEN SHE TOOK OVER AND ADDED POWER TO CLIMB SHE CLAIMED THE ENGINE DID NOT FULLY RESPOND. SHE WAS UNABLE TO CLEAR A POWER LINE, WHICH HAD REMAINED UNSEEN ON THE APPROACH, AND THE POWERLINES SLIGHT CONTACT WITH THE LANDING GEAR 'TRIPPED' THE ACFT INTO A 'HEAVY' LANDING WHICH COLLAPSED THE NOSE GEAR AND THE ACFT NOSED OVER. THE ACFT ENGINE HAD JUST BEEN ADJUSTED TO A LOWER IDLE SPEED PRIOR TO THIS FLT PER THE CFIS REQUEST. THE MECHANIC SAID THE ENGINE WAS 'WARM' DURING THE IDLE ADJUSTMENT. DURING POST ACCIDENT EXAM THE COMPRESSION ON CYLINDERS #1 & #4 WAS VERY WEAK AND THEY WERE STAKED TO GET AN IMPROVEMENT. THE LOWER PLUGS WERE NOTED TO BE COATED WITH BLACK OIL. THE MAGS CHECKED AS NORMAL.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
