Steep Climb and Uncontrolled Descent During Takeoff National Air Cargo, Inc., dba National Airlines, Boeing 747 400 BCF, N949CA, Bagram, Afghanistan, April 29, 2013. Publication Type NTSB/AAR-15/01. Washington, DC. Abstract: This report discusses the April 29, 2013, accident involving a Boeing 747-400 BCF, N949CA, operated by National Air Cargo, Inc., dba National Airlines, which crashed shortly after takeoff from Bagram Air Base, Bagram, Afghanistan. All seven crewmembers—the captain, first officer, loadmaster, augmented captain and first officer, and two mechanics—died, and the airplane was destroyed from impact forces and postcrash fire. Safety issues relate to National Airlines’ deficient procedures for restraining special cargo loads; inadequate Federal Aviation Administration (FAA) guidance for operators for restraining special cargo loads; the lack of FAA certification for cargo handling personnel and, thus, a lack of standardized procedures, training, and duty hour limitations and rest requirements for personnel who perform the safety-critical functions of loading and securing cargo; inadequate training and guidance for FAA inspectors who have oversight responsibilities for air carrier cargo handling operations; and the ability to defer nonresourced FAA surveillance items without limitation. Safety recommendations are addressed to the FAA. The National Transportation Safety Board (NTSB) is an independent federal agency dedicated to promoting aviation, railroad, highway, marine, and pipeline safety. Established in 1967, the agency is mandated by Congress through the Independent Safety Board Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The NTSB makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and statistical reviews. The NTSB does not assign fault or blame for an accident or incident; rather, as specified by NTSB regulation, “accident/incident investigations are fact-finding proceedings with no formal issues and no adverse parties … and are not conducted for the purpose of determining the rights or liabilities of any person.” 49 C.F.R. § 831.4. Assignment of fault or legal liability is not relevant to the NTSB’s statutory mission to improve transportation safety by investigating accidents and incidents and issuing safety recommendations. In addition, statutory language prohibits the admission into evidence or use of any part of an NTSB report related to an accident in a civil action for damages resulting from a matter mentioned in the report. 49 U.S.C. § 1154(b).
