In accordance with the provisions in Article 5.4.1 of Annex 13 of the International Civil Aviation Convention; and with articles 5.5 of Regulation (UE) nº 996/2010, of the European Parliament and the Council, of 20 October 2010; Article 15 of Law 21/2003 on Air Safety and articles 1., 4. and 21.2 of Regulation 389/1998, this investigation is exclusively of a technical nature, and its objective is the prevention of future civil aviation accidents and incidents by issuing, if necessary, safety recommendations to prevent from their reoccurrence. The investigation is not pointed to establish blame or liability whatsoever, and it’s not prejudging the possible decision taken by the judicial authorities. Therefore, and according to above norms and regulations, the investigation was carried out using procedures not necessarily subject to the guarantees and rights usually used for the evidences in a judicial process. Consequently, any use of this report for purposes other than that of preventing future accidents may lead to erroneous conclusions or interpretations. This report was originally issued in Spanish.

According to the pilot’s statement, the cockpit canopy opened unexpectedly while at an altitude of about 700- 750 ft (600 ft-650 above ground level). The pilot was unable to close the canopy without releasing the flight controls. The open canopy caused a great instability in the elevator and control stick, making it very difficult for the pilot to control the aircraft. In the

COCHRAN Conducted IAW Air Force Instruction 51-503 [Volume One of Two] //Signed// United States Air Force Accident Investigation Board Report F-16C Mishap, Clinton, MD EXECUTIVE SUMMARY UNITED STATES AIR FORCE AIRCRAFT ACCIDENT INVESTIGATION F-16C, T/N 87-0306 CLINTON, MD 5 APRIL 2017 On 5 April 2017, at 09:13 hours local time (L), an F-16C impacted the ground southwest of Joint Base Andrews (JBA), in Clinton, Maryland (MD). The mishap pilot (MP) safely ejected and did not sustain any injuries. The mishap aircraft (MA) tail number 87-0306 and the MP are assigned to the 113th Wing, 121st Fighter Squadron, JBA, MD. The MA, valued at $22,198,075, was destroyed. The MA’s two external fuel tanks were jettisoned prior to MP ejection and impacted private property located east of the Potomac River shoreline and approximately 1,750 feet south of National Harbor, MD. The MA impacted a wooded area 3.4 nautical miles southwest of JBA. There were no personnel injured on the ground. The area upon which the MA and external fuel tanks landed was disturbed by the respective impacts, resulting fireball (from the MA), and associated fluids and debris. The environmental clean-up cost was $856,777. The mishap occurred as part of a four aircraft F-16 formation on departure from JBA.

However, personnel may have to gain access under exceptional circumstances, where there is a risk to life. Cockpit canopies A military aircraft cockpit is covered and protected by a canopy. Canopies can weigh in the region of 100kg and are constructed from a strong, heavy and usually transparent material. The emergency canopy release may be activated accidentally or by aircrew as personnel are approaching or working near the aircraft. Ejection seats When an aircraft is parked on the ground, safety devices, in the form of distinctive safety pins, are fitted to prevent the accidental actuation of the ejection seat. Following an emergency, the status of the ejection seats may be unknown. If the seat guide rails projecting out of the canopy area are visible, it can indicate that the seats have fired from the cockpit and the aircrew may be some distance from the airframe. Personnel should not assume the ejection seats have activated successfully; for example, a two-seat aircraft may have had only one occupant, or a seat may have failed to operate.

  • Foot Forces Exerted at Various Aircraft Brake-Pedal Angles
    HUMAN FACTORS, 1971, 13(5), 445-456 Foot Forces Exerted at Various Aircraft Brake-Pedal Angles H. T. E. HERTZBERG and FRANCIS E. BURKEl, Anthropology Branch, Aerospace Medical Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio This study reports the forces (means and standards deviations) exerted by the foot at various angles of extension about its ankle. A sample of 100 rated pilots was selected by height and weigh t. The forces were measured in a cockpif mock-up constructed around a specially instrumented F-80 rudder·pedal assembly. The right rudder pedal (hinged on the rudder bar) could be rigidly set to any desired angle between vertical and 75° forward of vertical. Foot forces were measured at 11 positions of the instrumented brake pedal in both neutral and extended positions of the right leg, and in three cockpit sizes (37 in., 3914 in., and 41 in.)-66 measures on each man. In all three conditions, maximal forces were exerted within a 20° zone between 15 and 35° forward of vertical. Subjective comfort preferences, expressed by 86 pilots, closely paralleled the force findings. It is concluded that aircraft brake-pedal systems should be designed to maximize the effectiveness of the foot in that optimal zone, and that the same zone should be considered for other foot-operated controls, like automobile accelerator pedals, INTRODUCTION can exert its maximum torque about the ankle, as well as the magnitude of the forces them- Anyone who does work with his muscles selves.
