## Probable cause

INADVERTENT STALL/MUSH BY THE PILOT-IN-COMMAND RESULTING IN THE UNCONTROLLED DESCENT AND COLLISION WITH TERRAIN.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

WITNESSES REPORTED THAT AFTER TAKEOFF THE AIRPLANE CLIMBED TO ABOUT 150 FEET ABOVE GROUND LEVEL THEN PITCHED NOSE DOWN AND DESCENDED NOSE LOW.  ACCORDING TO FAA PERSONNEL, THE AIRPLANE IMPACTED THE GROUND NOSE AND RIGHT WING LOW. EXAMINATION OF THE FLIGHT CONTROLS REVEALED NO EVIDENCE OF PREIMPACT FAILURE OR MALFUNCTION.  THE ENGINE WAS STARTED AFTER REPLACEMENT OF IMPACT DAMAGED COMPONENTS AND MINOR ADJUSTMENT OF THE POINTS.  THE ENGINE STARTED AND OPERATED NORMALLY.

## Factual narrative

HISTORY OF FLIGHT

On June 1, 1994, about 1458 eastern daylight time, an unregistered Maxair Aircraft Corporation MU532, crashed shortly after takeoff from a sod farm near Kissimmee, Florida, while on a 14 CFR Part 91 personal flight.  Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was destroyed and the student pilot, the sole occupant, was fatally injured.  The flight originated about 5 minutes earlier.

A witness reported seeing the airplane climb to about 150 feet after takeoff, then observed the airplane pitch nose down and impact the ground.  The witnesses could not hear any sounds from the engine because of noise nearby.  The airplane owner stated that the pilot did not have verbal or written permission to fly or operate the airplane.

PERSONNEL INFORMATION

Information pertaining to the first pilot is contained in the NTSB Factual Report-Aviation.

AIRCRAFT INFORMATION

The airplane was not registered with the FAA and no logbooks were prepared for documenting maintenance.

METEOROLOGICAL INFORMATION

Information pertaining to weather is contained in the NTSB Factual Report-Aviation.

WRECKAGE AND IMPACT

An on-scene investigation was conducted by the FAA which revealed that the airplane impacted the ground nose and right wing low.  The fuel quantity was determined to be sufficient to sustain engine operation and examination of the airframe revealed no evidence of flight control failure or malfunction.  The engine was removed at a later date and after replacement of impact damaged components, and minor adjustment of the points, the engine was started and found to operate normally.

MEDICAL AND PATHOLOGICAL

A postmortem examination was conducted on the pilot by William R. Anderson, M.D., Deputy Chief Medical Examiner, Orlando, Florida.  The cause of death was listed as aortic transection, secondary to blunt force deceleration injuries, resulting from aircraft crash.  Atherosclerotic coronary artery disease with 75 percent and 50 percent stenosis were noted from the left anterior descending coronary artery and left circumflex coronary artery.  There was no evidence of acute myocardial necrosis.

A toxicological analysis of specimens of the pilot was performed by the FAA Toxicology and Accident Research Laboratory. The results were negative for carbon monoxide, cyanide,  volatiles, and tested drugs.
