BA) is reluctant to fly its test fleet of five 787 Dreamliners until problems relating to the jets' horizontal stabilizers
Alaska Air announces plans to inspect the horizontal stabilizers
in all of its MD-80 and MD-90 jetliners.
The computer numerically controlled machine can store up to 300 programs to roll complex shapes for airplane fuselages, wing leading edges, horizontal stabilizer
leading edges, and tail cones.
The MD-83, which was returning to San Francisco from Puerto Vallarta, was flying less than full when pilots began haying trouble with the positioning of the horizontal stabilizer
located in the plane's tail and requested an emergency landing at Los Angeles International airport.
The horizontal stabilizer
and vertical fin are integrated into Section 48 at Boeing final assembly.
Here is a capsule summary of the status of the 787-9 and 787-10 programs: Boeing said the Hybrid Laminar Flow Control system on the tail fin and horizontal stabilizer
of the 787-9 produced "significant" reduction in aerodynamic drag in testing, but the company declined to be specific.
Enter the horizontal stabilizer
, which in simple form is an airfoil mounted upside down.
The directive, which is not related to any event or occurrence, refers to an issue with the protective coating on pins located in the horizontal stabilizer
rear spar, which attach the main stabilizers to the fuselage.
According to the report, the US aviation authority said premature failure of the pins could cause reduced structural integrity of the horizontal stabilizer
to fuselage attachment, resulting in loss of control of the airplane.
After orbiting for two hours during a tactically task-saturated portion of the mission, our starboard observer noticed that the high-frequency (HF-2) wire had detached and wrapped around the horizontal stabilizer
F-18D's right horizontal stabilizer
to hit the wall of the revetment.
The starboard trailing edge flap, starboard horizontal stabilizer
and both engines sustained damage, but the aircraft was flyable.
