Component Affected: Aircraft structure and electrical systems.Aircraft structure and electrical systems.
Investigating Agency: CIDAIA MexicoCIDAIA Mexico
Category: Accident
A BAe-125 corporate jet crashed in an accident at Ramos Arizpe, Mexico, resulting in the deaths of all eight occupants. The aircraft struck high-tension electrical cables, causing a crash into an industrial park while approaching Runway 17 at Saltillo-Plan de Guadalupe International Airport (SLW). Visibility was reduced to 800 meters (2600 feet) due to fog and overcast, with a 200-foot height above ground level. The probable cause was an impact against high-voltage electrical power cables, leading to loss of control and subsequent crash. The incident highlights deficiencies in approach procedures, decision-making regarding continued approach, maintenance practices, and operational safety culture.A BAe-125 corporate jet crashed in an accident at Ramos Arizpe, Mexico, resulting in the deaths of all eight occupants.

Description

A BAe-125 corporate jet was destroyed in an accident at Ramos Arizpe, Mexico. All eight on board suffered fatal injuries. The airplane struck high tension cables and crashed into an industrial park while on approach to runway 17 at Saltillo-Plan de Guadalupe International Airport (SLW). Visibility at the time of the accident was about 800 m (1/2 mile) in fog with an overcast at 200 feet above ground level. Probable cause: “Impact against high-voltage electrical power cables causing loss of control and the aircraft to crash, while flying without capturing the glide slope (GP) and descending below the decision height (DH) in an approach under conditions of reduced visibility due to the presence of an fog obstructing vision of the surface.” CONTRIBUTING FACTORS, – Unstabilized approach – Inadequate decision to continue an approach below MDA (Minimum Descend Altitude) without visual contact. – Poor company operational safety culture – Lack of adherence to ILS/DME2 runway 17 approach procedures published in the PIA. – Lack of application of CRM concepts – Lack of follow up and reaction to GPWS audible warning alarms “caution flaps” , “sink rate” and “terrain” “pull up” – Lack of altitude monitoring during approach. – Adverse weather conditions below minimums – Inadequate maintenance control – Lack of adherence to standard operating procedures (SOPS).
