## Sequence of events

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

- Loss of control - on ground/water, landing - aborted
  - directional control - inadequate, pilot in command (cause)
  - go-around - delayed, pilot in command (cause)
  - raising of flaps - delayed, pilot in command (contributing factor)
- Loss of control - in flight, landing - aborted
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - object - tree(s)

## Analysis

THE PILOT WAS PERFORMING A TOUCH AND GO LANDING AT BRANDWYINE AIRPORT AND LOST DIRECTIONAL CONTROL DURING LANDING. HE SAID HE TOUCHED DOWN, APPLIED FULL POWER THEN REMEMBERED TO PUT THE FLAPS UP. WHEN THE ACFT STARTED TO VEER OFF THE RWY THE PLT APPLIED BRAKES BUT WAS UNABLE TO REGAIN CONTROL. THE TERRAIN OFF THE RWY WAS DESCENDING. THE ACFT BECAME AIRBORNE BRIEFLY THEN STALLED AND COLLIDED WITH TREES TO THE RT OF THE RWY. THE PLT SAID THIS WAS HIS FIRST 'TOUCH AND GO' IN ABOUT 2 YEARS.
