## Probable cause

the student pilot not understanding the crew briefing, his premature retraction of the landing gear, and the flight instructor's inadequate supervision of the flight.  A factor relating to the accident was: the exchange of unclear information due to the student's language barrier.

## Sequence of events

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

- In flight collision with terrain/water, takeoff - aborted
  - crew/group briefing - not understood, dual student (cause)
  - information unclear(language), dual student (contributing factor)
  - throttle/power control - reduced, pilot in command(cfi)
  - rotation - performed, dual student
  - gear retraction - premature, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)

## Analysis

The flight instructor was giving rejected takeoff instruction to a foreign student. As power was increased, tower cancelled the takeoff clearance and instructed the pilot to 'hold in position.'  The instructor said the student did not understand the instruction, so he retarded engine power and repeated the clearance to the student. After repositioning the airplane for takeoff, he asked the student if he understood the clearance. The student acknowledged. After receiving takeoff clearance again, the instructor reduced power on the right engine, when the airplane was 10 mph below rotation speed. The student 'rotated (decided to fly), and the airplane became airborne.'  The instructor told the student to land the airplane as there was sufficient runway remaining. The student did not respond. The instructor attempted to land, but tower advised that the landing gear was not extended. The instructor applied full power on the right engine, but the airplane settled onto the runway.

## Factual narrative

On March 12, 1998, at 1608 mountain standard time, a Piper PA-34-200, N83DA, owned and operated by U.S. Aviation, was substantially damaged during takeoff at Ogden, Utah.  The commercial rated flight instructor and commercial rated pilot receiving instruction were not injured.  Visual meteorological conditions prevailed, and no flight plan was filed for the instructional flight being conducted under Title 14 CFR Part 91. The flight originated at Ogden approximately 1530.

According to the accident report submitted by the flight instructor, he was giving instruction in rejected takeoff procedures to a foreign student.  The instructor advised the control tower what his intentions were.  The pilot was cleared to "position and hold" on runway 21, and subsequently cleared for takeoff.  As power was increased, the control tower cancelled the takeoff clearance and instructed the pilot to "hold in position."  The instructor said the student did not understand the instruction.  The instructor retarded engine power and repeated the clearance to the student.  The student attempted to exit the runway.  The instructor took control of the airplane and repositioned it on the runway.  He repeated the clearance to the student and asked him if he understood.  The student acknowledged.

The instructor then advised the control tower that they would accept a normal takeoff clearance if it would be expedient.  He was advised to stand by and that he could perform his rejected takeoff procedure momentarily.  Shortly thereafter, they were cleared for takeoff.  The instructor said that when the airplane was 10 mph below rotation speed, he retarded the right engine throttle.  The student "rotated (decided to fly) and the airplane became airborne."  The instructor told the student to land the airplane as there was sufficient runway remaining.  The student did not respond.  The instructor again took control of the airplane and was getting ready to land when the control tower advised that the landing gear was not extended.  The instructor applied full power on the right engine, but the airplane settled onto the runway.  Postaccident inspection disclosed the left engine firewall was buckled.
