## Probable cause

A DELAYED BY THE PILOT IN GOING AROUND AND HIS FAILURE TO OBTAIN ADEQUATE AIRSPEED BEFORE FULLY RETRACTING THE FLAPS, WHICH ALLOWED THE AIRCRAFT TO MUSH. THE CONTRIBUTING FACTORS WERE: THE PILOT'S FAILURE TO ATTAIN THE PROPER TOUCHDOWN POINT DURING THE LANDING AND THE TRANSMISSION WIRE.

## Sequence of events

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

- In flight collision with object, landing - aborted
  - proper touchdown point - not attained, pilot in command (contributing factor)
  - go-around - delayed, pilot in command (cause)
  - raising of flaps - improper, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
  - object - wire,transmission (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

AFTER LANDING LONG, THE PLT ELECTED TO GO-AROUND. HE RETRACTED THE FLAPS TO FULL UP & THE ACFT STOPPED CLIMBING & STARTED SETTLING WITH THE STALL WARNING HORN SOUNDING. THE PLT OBSERVED WIRES IN HIS FLT PATH & ROTATED THE PLANE TO AN ATTITUDE WHICH WOULD ALLOW THE WIRE TO STRIKE THE ACFT'S BELLY, RATHER THAN ACROSS THE WINDSHIELD. AFTER THE WIRE STRIKE, THE ACFT DESCENDED OUT OF CONTROL & COLLIDED WITH THE TERRAIN. ACCORDING TO THE GO-AROUND PROCEDURE IN THE FLT MANUAL, THE FLAPS SHOULD HAVE BEEN RETRACTED TO ONLY 20 DEG UNTIL THE ACFT HAD ACCELERATED TO 75 MPH, THEN FURTHER FLAP RETRACTION SHOULD HAVE BEEN PERFORMED SLOWLY.

## Other investigations on N102AT (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.
