Here's a learning opportunity involving the effects of hangars on
crosswind correction, as well as soft-field operations. I used to rent
this aircraft and noticed that it disappeared from the flight line last
summer.


" 14 CFR Part 91: General Aviation...
Aircraft: Cessna 172M, registration: NXXXX
Injuries: 1 Uninjured.

During the takeoff roll in a 30 degree crosswind of about 12 knots, the
aircraft passed on the leeward side of a number of hangars of varying
size. As the aircraft passed through the area where the wind was blocked
by the individual hangars into areas where the wind was not blocked, the
student pilot failed to adequately compensate for the resultant change
in wind velocity and direction. As the student pilot continued the
takeoff, the aircraft departed the side of the runway, impacted a
taxiway exit sign, and entered into an area of wet, soft ground. The
student pilot then pulled the power to idle and applied "full brakes."
The nose gear then dug into the terrain and ultimately collapsed. There
were no anomalies found in the rudder or nose wheel steering systems.

The National Transportation Safety Board determines the probable
cause(s) of this accident as follows:
The student pilot's failure to adequately correct for changing wind
conditions, leading to a loss of directional control during the takeoff
ground roll. Factors include wet, soft terrain along the side of the
runway."

Have a safe and spectacular weekend!

I've been to many airports where the wind socks are all pointing in
different directions due to the airflow around buildings.
