## Probable cause

THE INADEQUATE SUPERVISION OF THE STUDENT BY THE FLIGHT INSTRUCTOR.  A FACTOR WAS:  THE STUDENT'S FAILURE TO FLARE THE AIRCRAFT.

## Sequence of events

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

- Hard landing, landing
  - supervision - inadequate, pilot in command(cfi) (cause)
  - flare - not performed, dual student (contributing factor)
  - lack of total experience, dual student (contributing factor)
- Nose gear collapsed, landing - flare/touchdown
- Nose down, landing - roll

## Analysis

THE INSTRUCTOR WAS TALKING THE STUDENT THROUGH THE LANDING.  HE TOLD HER TO FLARE THE AIRPLANE AND ASSISTED BY APPLYING ELEVATOR BACK PRESSURE.  HE SAID THE STUDENT, INSTEAD, APPLIED FORWARD PRESSURE.  THE INSTRUCTOR APPLIED FULL BACK PRESSURE BUT THE AIRPLANE STRUCK THE RUNWAY NOSE LOW ATTITUDE. THE STUDENT SAID THE AIRPLANE BEGAN TO YAW AND SHE CONCENTRATED ON ALIGNING THE AIRPLANE WITH THE RUNWAY. SHE HEARD THE INSTRUCTOR CALL FOR MORE POWER AND FELT A FORCEFUL NOSE DOWN PRESSURE. SHE SAID SHE DID NOT THINK SHE APPLIED ANY ELEVATOR BACK PRESSURE. ANOTHER FLIGHT INSTRUCOTR, WHO WAS AT THE END OF THE RUNWAY, WATCHED THE AIRPLANE APPROACH IN AN UNUSUALLY NOSE LOW ATTITUDE, AND SAID THERE WAS NO APPARENT ATTEMPT TO FLARE THE AIRPLANE.

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

- [Accident 19910121001559A](https://openairdocs.org/incident/19910121001559A), Jan 21, 1991: Cessna 152, Tulsa, OK, Substantial damage. Student panicked on landing and CFI was unable to flair aircraft against students nosed down pressure.

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.
