Safety Concerns at Washington Metropolitan Area Transit Authority (WMATA) and Implications for Ridership The Metro network operated by the Washington Metropolitan Area Transit Authority (WMATA) provides mass transportation for the nation's capital region for visitors, residents and especially members of the federal government workforce. Besides 118 miles of rail tracks and 91 stations (making it the nation's second-largest heavy rail transit system), the Metro also operates the fifth largest paratransit service

The NAAP structural integrity program includes three tests including Widespread Fatigue Damage (WFD), Damage tolerance analysis (DTA) and DTA based airframe repair assessment. The supplemental inspection programs of the FAA ensure that commercial airlines fulfill the structural safety requirements. Any structural defects that are observed during the normal operation of an airplane or those that are revealed after an accident are issued as Airworthiness Directives (AD). The FAA periodically

U.S. statistics indicate that 80% of aviation accidents are due to human errors with 50% due to maintenance human factor problems. Current human factor management programs have not succeeded to the degree desired. Many industries today use performance excellence frameworks such as the Baldrige National Quality Award framework to improve over-all organizational effectiveness, organizational culture and personal learning and growth. A survey administered to a sample population of senior aviation

The following definitions may be helpful. Category 1 APUs are installed where in-flight auxiliary power operation is necessary. Category 1 APUs are usually required for essential APU installations. These APUs have been shown to meet all of the test and analysis requirements of the Minimum Performance Standard (MPS) of TSO C77b, Appendix 1. Category 2 APUs are installed where in-flight APU operation is not necessary (non-essential installations). Both Category 1 and Category

This category can further be divided into six subgroups namely; short-range, medium range, long-range, close range, endurance, Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs). The long-range UAVs are technologically more advanced as they use satellites in order to overcome the communication problem between the UAVs and the ground stations. This communication problem is generally caused by the curvature of the earth. The medium, short and close range

Moreover, the study compares the effect on human factors on different types of aircraft. The study also reveals the correlation between the anomalies and type of aircrafts. Human factors cause of Aircraft Accidents The results of the descriptive statistics reveal that situational awareness is the most contributing human factor to aircraft accidents with the Mean =112. Moreover, the Mean value of the communication breakdown is 80 which rank second as the
