## Analysis (aircraft 2)

N251NW WAS DEPARTING ON RUNWAY 2 AND N2632U WAS LANDING ON RUNWAY 10.  THE AIRPLANES COLLIDED AT THE INTERSECTION OF THE TWO RUNWAYS.  A WEATHER OBSERVATION MADE FIFTEEN MINUTES AFTER THE ACCIDENT INDICATED AN OVERCAST CLOUD LAYER AT 2000 FEET, 3 MILES VISIBILITY, AND WINDS OUT OF 070 DEGREES AT 3 KNOTS.  BOTH PILOTS STATED THEY COMMUNICATED THEIR INTENTIONS ON THE UNICOM FREQUENCY.  AIRPORT PERSONNEL ADVISED THEY HEARD TRANSMISSIONS FROM THE AIRPLANE INBOUND FOR LANDING.  BOTH PILOTS STATED THEY DID NOT SEE THE OTHER AIRPLANE UNTIL JUST PRIOR TO IMPACT.  THE PILOT OF N251NW REPORTED THAT HE CHECKED THE GAUGES OF HIS AIRCRAFT DURING THE TAKEOFF ROLL AFTER HAVING HAD A PREVIOUS MAGNETO TIMING PROBLEM.
