LOC-G: Loss of control - ground - Loss of aircraft control while the aircraft is on the ground.
- Used only for non-airborne phases of flight, i.e., ground/surface operations.
- The loss of control may result from a contaminated runway or taxiway (e.g., rain, snow, ice, slush).
- The loss of control during ground operations can occur as the result of other occurrence categories as well. For example, LOC-G may result from a system/component failure or malfunction to the powerplant (SCF-PP) or non-powerplant (SCF-NP), or from evasive action taken during a Runway Incursion (RI-VAP, or RI-A). For these occurrences, the event is coded under both categories (e.g., LOC-G and SCF-PP, LOC-G and SCF-NP, or LOC-G and RI-VAP or RI-A).
- Do not use when a mechanical failure rendered the aircraft uncontrollable.
- Rotorcraft during sloping ground or moving helideck operations, dynamic rollover and ground resonance events are also included here.
