## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - weather condition - windshear (contributing factor)
  - weather condition - clouds (contributing factor)
  - compensation for wind conditions - exceeded, pilot in command (cause)
  - proper descent rate - exceeded, pilot in command (cause)
- Main gear collapsed, landing - flare/touchdown
  - landing gear,main gear - overload

## Analysis

ACCORDING TO THE PLT, WITH FULL FLAPS EXTENDED THE ACFT ENCOUNTERED A WINDSHEAR DURING THE FLARE CAUSING AN EXCESSIVE RATE OF DESCENT ON TOUCHDOWN. RWY CONTACT COLLAPSED THE LEFT MAIN LANDING GEAR ALLOWING THE LEFT WING TO SCRAPE ON THE RWY. SHORTLY BEFORE LANDING ALTUS AIR FORCE BASE ADVISED THE PLT OF WINDS FROM THE SW AT 19 KTS GUSTING TO 29.
