Primary Problem | Flight Crew Human Performance |
Narrative:
A normal approach to a straight-in landing was accomplished. Touchdown was on speed and in the zone. Autobrakes were on setting #1 with the speed brakes armed. On touchdown, when the brakes came on, the person flying overcompensated when the nose came down quickly. The nose was held off too high, causing a slight tailskid strike. The rollout and taxi in were normal. The cause of the problem was overcompensation for nose gear touchdown. The solution could perhaps be more education on the subject of autobrake and nose gear/tail strike awareness. Supplemental information from acn 452360: the following human performance considerations contributed to this incident: 1) the captain reduced power in the flare too soon with a touchdown speed of target (bug) speed -- 5 KTS. 2) the captain landed in a higher than normal nose high attitude to adjust for lack of airspeed. 3) the captain failed to correct for the nose pitch up due to automatic spoiler activation. 4) I believe the captain was fatigued due to 2 consecutive duty periods of 11 hours. 5) had the captain used autobrakes which counteract the spoiler pitch, the incident could have been avoided.

Title: A B767-300 FLC HAD THE TAIL SKID CONTACT THE RWY ON LNDG AT ATL.
Narrative: A NORMAL APCH TO A STRAIGHT-IN LNDG WAS ACCOMPLISHED. TOUCHDOWN WAS ON SPD AND IN THE ZONE. AUTOBRAKES WERE ON SETTING #1 WITH THE SPD BRAKES ARMED. ON TOUCHDOWN, WHEN THE BRAKES CAME ON, THE PERSON FLYING OVERCOMPENSATED WHEN THE NOSE CAME DOWN QUICKLY. THE NOSE WAS HELD OFF TOO HIGH, CAUSING A SLIGHT TAILSKID STRIKE. THE ROLLOUT AND TAXI IN WERE NORMAL. THE CAUSE OF THE PROB WAS OVERCOMPENSATION FOR NOSE GEAR TOUCHDOWN. THE SOLUTION COULD PERHAPS BE MORE EDUCATION ON THE SUBJECT OF AUTOBRAKE AND NOSE GEAR/TAIL STRIKE AWARENESS. SUPPLEMENTAL INFO FROM ACN 452360: THE FOLLOWING HUMAN PERFORMANCE CONSIDERATIONS CONTRIBUTED TO THIS INCIDENT: 1) THE CAPT REDUCED PWR IN THE FLARE TOO SOON WITH A TOUCHDOWN SPD OF TARGET (BUG) SPD -- 5 KTS. 2) THE CAPT LANDED IN A HIGHER THAN NORMAL NOSE HIGH ATTITUDE TO ADJUST FOR LACK OF AIRSPD. 3) THE CAPT FAILED TO CORRECT FOR THE NOSE PITCH UP DUE TO AUTOMATIC SPOILER ACTIVATION. 4) I BELIEVE THE CAPT WAS FATIGUED DUE TO 2 CONSECUTIVE DUTY PERIODS OF 11 HRS. 5) HAD THE CAPT USED AUTOBRAKES WHICH COUNTERACT THE SPOILER PITCH, THE INCIDENT COULD HAVE BEEN AVOIDED.
