## Probable cause

THE PILOT'S POORLY PLANNED APPROACH, HIS USE OF AN EXCESSIVE AIRSPEED ON FINAL APPROACH AND HIS IMPROPER USE OF THE BRAKES.  A FACTOR IN THE ACCIDENT WAS HIS LIMITED EXPERIENCE IN BOTH MULTI ENGINE AND IN THE ACCIDENT AIRCRAFT.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - planned approach - poor, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
  - airspeed(vref) - excessive, pilot in command (cause)
  - brakes(normal) - improper use of, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- Main gear collapsed, landing - roll
  - landing gear,main gear - overload

## Analysis

THE ACCIDENT WAS WITNESSED BY BOTH AIR TRAFFIC CONTROLLERS IN THE TOWER CAB AND VARIOUS PILOTS AND MECHANICS AT THE AIRPORT. ACCORDING TO THEIR OBSERVATIONS, THE AIRCRAFT'S FINAL APPROACH WAS 'HOT, HIGH AND LONG.' THE AIRCRAFT TOUCHED DOWN ABOUT TWO THIRDS OF THE WAY DOWN THE RUNWAY AND SHORTLY THEREAFTER BEGAN TO SKID. THE AIRCRAFT BEGAN TO SKID SIDEWAYS AND A MAIN LANDING GEAR COLLAPSED. THE PILOT SAID THAT HE ENCOUNTERED A TAIL WIND ON FINAL WHICH CAUSED HIS AIRSPEED TO BE EXCESSIVE AND THE AIRCRAFT TO FLOAT.  HE FURTHER REPORTED THAT JUST AFTER TOUCHDOWN WHEN THE AIRCRAFT WAS SKIDDING HE REACHED FOR THE FLAP CONTROL LEVER. THE AIR TRAFFIC CONTROLLERS IN THE TOWER CAB REPORTED THAT THE WINDS WERE CALM AT THE TIME OF THE AIRCRAFT'S APPROACH AND LANDING.

## Other investigations on N4458S (1)

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.

Probable cause: the pilot's failure to remain above the landing Boeing 757's glide path resulting in an encounter with wing tip vortices, a loss of directional control after touchdown, and collision with taxiway…
