<< >> NASA ASRS Report 375580, August 1997

Small transport aircraft in cruise and in radio contact with approach control but not yet radar idented had near midair collision with small aircraft aircraft. Reporter says other pilot was not taking evasive action and reporter's lack of adequate scan was partially due to fatigue.

Narrative:

Having just completed a routine 2 hour flight review at pwk, I was returning to base at arrival, remaining north of ord. I was in touch with ord approach to set up flight following through the area, but radar was not confirmed as yet (it was, a few mins later). A very small (home built?) low wing aircraft passed from left to right in front of me (northbound). In the few seconds I saw him, I don't think the other pilot was taking evasive action. Thoughts: a bad reminder that one can't get preoccupied with cockpit duties, especially in crowded areas, especially when tired (I had just completed 2 hours or so of intensive training including 6 approachs (1 real) engine out, etc). I should have been horizon scanning better!

Original NASA ASRS Text

Title: SMT ACFT IN CRUISE AND IN RADIO CONTACT WITH APCH CTL BUT NOT YET RADAR IDENTED HAD NMAC WITH SMA ACFT. RPTR SAYS OTHER PLT WAS NOT TAKING EVASIVE ACTION AND RPTR'S LACK OF ADEQUATE SCAN WAS PARTIALLY DUE TO FATIGUE.

Narrative: HAVING JUST COMPLETED A ROUTINE 2 HR FLT REVIEW AT PWK, I WAS RETURNING TO BASE AT ARR, REMAINING N OF ORD. I WAS IN TOUCH WITH ORD APCH TO SET UP FLT FOLLOWING THROUGH THE AREA, BUT RADAR WAS NOT CONFIRMED AS YET (IT WAS, A FEW MINS LATER). A VERY SMALL (HOME BUILT?) LOW WING ACFT PASSED FROM L TO R IN FRONT OF ME (NBOUND). IN THE FEW SECONDS I SAW HIM, I DON'T THINK THE OTHER PLT WAS TAKING EVASIVE ACTION. THOUGHTS: A BAD REMINDER THAT ONE CAN'T GET PREOCCUPIED WITH COCKPIT DUTIES, ESPECIALLY IN CROWDED AREAS, ESPECIALLY WHEN TIRED (I HAD JUST COMPLETED 2 HRS OR SO OF INTENSIVE TRAINING INCLUDING 6 APCHS (1 REAL) ENG OUT, ETC). I SHOULD HAVE BEEN HORIZON SCANNING BETTER!
