EASA SIB 2018-07: Blood Alcohol Concentration Limits for General Aviation Pilots

What to do

Pilots should ensure their blood and breath alcohol levels do not exceed the recommended limits and avoid alcohol consumption for at least 8 hours before flight duties. Aero clubs and pilot training organizations should incorporate these recommendations into their safety and risk management practices. Competent authorities should consider these guidelines during oversight activities but note that the recommendations are not mandatory and no compliance deadlines are specified.

Summary

EASA Safety Information Bulletin No. 2018-07 is a guidance document addressing blood alcohol concentration limits for General Aviation pilots, including those involved in non-commercial aerial work. It provides recommendations on maximum blood and breath alcohol levels and advises on alcohol consumption timing relative to flight duties. The bulletin applies broadly to General Aviation pilots, aero clubs, pilot training organizations, and EASA Member States’ competent authorities.

What changed

This new Safety Information Bulletin introduces recommended blood alcohol concentration limits for General Aviation pilots, emphasizing that pilots should not exceed a BAC of 0.02% or a BrAC of 90 micrograms per litre while performing flight-related duties. It also recommends abstaining from alcohol for at least 8 hours before operating an aircraft, highlighting that this period may not guarantee compliance with limits depending on alcohol quantity consumed.

Why it matters

This bulletin is important for aviation professionals because it clarifies the safety risks associated with alcohol consumption before flying and reinforces regulatory expectations under existing EU aviation regulations. Operators, training organizations, and oversight authorities can use these guidelines to enhance risk management and ensure pilot fitness for duty, thereby improving flight safety in General Aviation.
