## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - mech failure/malf, takeoff - initial climb
  - induction air control/system - blocked(total) (cause)
- Forced landing, landing - flare/touchdown
- In flight collision with object, landing - flare/touchdown
  - object - tree(s)

## Analysis

WHILE ON CROSSWIND FOLLOWING TAKEOFF THE ENGINE LOST TOTAL POWER AFTER CLIMBING TO 500 FEET AGL. THE PILOT INITIATED A TURN TOWARD A FIELD AND COLLIDED WITH TREES ON THE APPROACH END OF THE FIELD. POST-CRASH EXAMINATION OF THE AIRCRAFT REVEALED THAT THE INDUCTION AIR HOSE HAD COLLAPSED AND WAS DRAWN INTO THE INDUCTION SYSTEM, RESTRICTING THE FLOW OF INDUCTION AIR TO THE ENGINE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19860209002389A](https://openairdocs.org/incident/19860209002389A), Feb 9, 1986: Grtlks 2T1A2, Columbia, SC, Substantial damage. Struck trees after engine power loss during takeoff. Air induction duct collapsed, restricting air flow to engine.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
