## Probable cause

The flight instructor's failure to maintain pitch control and his improper landing flare, which resulted in a hard landing.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Performance/control parameters: pitch control](https://openairdocs.org/ntsb-findings/01062022): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Ercoupe 415-C, 1 case](https://openairdocs.org/ntsb-findings/01062022/cases.md?model=0420322), [All aircraft, 526 cases](https://openairdocs.org/ntsb-findings/01062022/cases.md)
- [Performance/control parameters: landing flare](https://openairdocs.org/ntsb-findings/01062041): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Ercoupe 415-C, 2 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md?model=0420322), [All aircraft, 1,285 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md)
- [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Instructor/check pilot (probable cause); cases with it: [Ercoupe 415-C, 9 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=0420322), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing: Simulated/training event](https://openairdocs.org/ntsb-events/600); cases with it: [Ercoupe 415-C, 1 case](https://openairdocs.org/ntsb-events/600/sequence.md?model=0420322), [All aircraft, 173 cases](https://openairdocs.org/ntsb-events/600/sequence.md)
- [Landing: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [Ercoupe 415-C, 3 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=0420322), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

The flight instructor reported that he was going to demonstrate a simulated engine failure on takeoff for the student pilot. After climbing the airplane several hundred feet, he reduced the engine power to idle and pitched the airplane to maintain best glide speed. He applied back pressure to the yoke during the landing flare and realized the airplane was going to land harder than desired. The airplane landed hard on the runway. The airplane sustained substantial damage to both wings. The instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
