NTSB Safety Recommendation — Aviation

Recommendation text

THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT ALL FAA-APPROVED BOEING 757/767 OPERATING MANUALS, AND OTHER AIRPLANE MODEL OPERATING MANUALS AS DEEMED APPROPRIATE, CLEARLY COMMUNICATE DEROTATION TECHNIQUES AND THE POTENTIAL FOR EXCESSIVE PITCH RATES AFTER TOUCH DOWN IF PILOTS USE LARGE NOSE-DOWN CONTROL COLUMN DEFLECTIONS. SUCH INFORMATION SHOULD BE INSERTED IN THE SECTIONS OF THE MANUAL THAT REFER TO NORMAL AND CROSSWIND APPROACH AND LANDING, AS A CAUTIONARY NOTE. INSTRUCTIONS CALLING FOR POSITIVE FORWARD CONTROL PRESSURE AFTER NOSE WHEEL TOUCHDOWN SHOULD BE REPLACED WITH A WARNING TO SMOOTHLY FLY THE NOSE WHEEL TO THE RUNWAY BY RELAXING AFT CONTROL COLUMN PRESSURE AND NOT TO USE FULL DOWN ELEVATOR.

In plain language (FlightFinder summary)

The Federal Aviation Administration is asked to require that operating manuals for Boeing 757/767 and other aircraft models clearly describe derotation techniques and warn about the risk of excessive pitch rates after touchdown if large nose-down control column deflections are used. This cautionary information should be placed in the normal and crosswind approach and landing sections. Instructions calling for positive forward control pressure after nose wheel touchdown should be replaced with a warning to smoothly fly the nose wheel to the runway by relaxing aft control pressure and not using full down elevator.

This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
