Air Traffic Incident | Pilot Deviation |
Narrative:
After takeoff, runway 03 with sat departure. Cleared to turn right heading 120 degrees climb and maintain 5000 ft. Nearby another traffic, a boeing 737 airliner, that was cleared to maintain 6000 ft and making a crossing path of about 90 degrees, crossing from left to right (approximately) and getting as close as almost 1/2 mi horizontal. At the time after I was instructed by the controller 3 times (approximately) to 'descend immediately,' I reacted. The evasive action was to reduce the power levers to flight idle at the time applying full forward elevator force to reach as soon as possible the assigned 5000 ft. A contributing factor was low field elevation (I'm more used to higher fields) inefficient trim action had been taken, to counteract the inertia of the airplane to continue climbing, also because of the high performance climb of the metropolitan III (fairchild), altitude alert was out of service (reported on the airplane logbook). All of these factors in conjunction with in the last 1 year period I have accumulated 945:00 hours and in the last month 90:00 hours, accumulated fatigue also by excessive noise exposure due to garret turboprop engines (even though we use headphones).
Original NASA ASRS Text
Title: ALTDEV ALT OVERSHOT. THIS ACR CAPT CLBED BEYOND HIS CLRNC LIMIT AND DID NOT HEAR THE CTLR'S CALLS UNTIL THE THIRD ONE. HE THEN APPLIED RATHER, NECESSARILY, ABRUPT CTL INPUTS TO CORRECT.
Narrative: AFTER TKOF, RWY 03 WITH SAT DEP. CLRED TO TURN R HDG 120 DEGS CLB AND MAINTAIN 5000 FT. NEARBY ANOTHER TFC, A BOEING 737 AIRLINER, THAT WAS CLRED TO MAINTAIN 6000 FT AND MAKING A XING PATH OF ABOUT 90 DEGS, XING FROM L TO R (APPROX) AND GETTING AS CLOSE AS ALMOST 1/2 MI HORIZ. AT THE TIME AFTER I WAS INSTRUCTED BY THE CTLR 3 TIMES (APPROX) TO 'DSND IMMEDIATELY,' I REACTED. THE EVASIVE ACTION WAS TO REDUCE THE PWR LEVERS TO FLT IDLE AT THE TIME APPLYING FULL FORWARD ELEVATOR FORCE TO REACH AS SOON AS POSSIBLE THE ASSIGNED 5000 FT. A CONTRIBUTING FACTOR WAS LOW FIELD ELEVATION (I'M MORE USED TO HIGHER FIELDS) INEFFICIENT TRIM ACTION HAD BEEN TAKEN, TO COUNTERACT THE INERTIA OF THE AIRPLANE TO CONTINUE CLBING, ALSO BECAUSE OF THE HIGH PERFORMANCE CLB OF THE METRO III (FAIRCHILD), ALT ALERT WAS OUT OF SVC (RPTED ON THE AIRPLANE LOGBOOK). ALL OF THESE FACTORS IN CONJUNCTION WITH IN THE LAST 1 YEAR PERIOD I HAVE ACCUMULATED 945:00 HRS AND IN THE LAST MONTH 90:00 HRS, ACCUMULATED FATIGUE ALSO BY EXCESSIVE NOISE EXPOSURE DUE TO GARRET TURBOPROP ENGS (EVEN THOUGH WE USE HEADPHONES).
