GA flights for maintenance checks, ferry, and engine health under COVID-19

The Government's guidance permits essential maintenance activity to take place during the current COVID-19 restrictions, and on this basis owners / operators of GA aircraft are permitted to conduct aircraft maintenance flights on the following basis:

  • Maintenance flights. Post-maintenance check flights in accordance with CAP1038 are permitted but must be kept to an absolute minimum in terms of both the number and duration of flights. They must be conducted in strict accordance with the approved maintenance or flight test profile.
  • Ferry flights. Flights to or from maintenance facilities for essential maintenance are permitted if such a facility is not available at the aircraft's current location. Flights are to be by the most direct practical route with transits flown at no lower than 1,000 feet Above Ground Level (AGL).
  • Engine health flights. The main way of maintaining engine health during COVID restrictions should be through winterisation or inhibition. Engine health flights are only permitted, where required by the engine manufacturer or equivalent LAA/BMAA procedures for Permit-to-Fly aircraft. Flights must follow those procedures and there must be a four-week gap between flights. Each flight must be no more than 30 minutes (or as recommended by the engine manufacturer in order to prevent internal engine corrosion). Aircraft should aim to remain within the airfield circuit. Unless safety of flight requirements dictate, the aircraft should not travel beyond a 10nm radius of its departure aerodrome and no dynamic manoeuvring activity should be flown. Each flight should be at the highest practical height to minimise to the noise impact on members of the public maintaining social distancing, and not below 1,000ft AGL except for take-off, approach and landing. If the engine manufacturer's instructions indicate that the engine only needs to be run at idle or at low power whilst on the ground and no other essential maintenance is required, then no flight may be performed.
  • Criteria for the conduct of these flights:
  • while the UK Government's social distancing policy is in place the owner or organisation operating the aircraft must maintain a log of all the aircraft movements. As a minimum, this must include the purpose of the flight, the aircraft registration, the pilot and their licence number, the flight's date, time and duration. This log is to be kept and if required provided immediately in electronic form to the CAA.
  • Only solo flights by fully qualified pilots are permitted. No other flights, including instructional sorties are allowed.  Aircraft must not be rented-out or flown for financial gain.
  • Aircraft must have a valid airworthiness certificate (CofA, Permit or Permit Flight Release Certificate) before a maintenance, ferry or engine health flight can take place.
  • These provisions apply equally to UK-registered and non-UK registered GA aircraft operating in UK airspace.
  • Any requests for exceptions to these provisions are to be submitted to a minimum of 10 days in advance of the requested date of the flight. 
  • At all times, the measures outlined by the UK Government to reduce the risk of the spread of COVID-19, such as social distancing, personal hygiene and minimising travel remain applicable, and pilots and operators undertaking flights on the basis permitted here must observe these. Aerodrome operators must also ensure that such flights are coordinated so that social distancing measures are not compromised at their location.

The information can be found here on the CAA website. You will need to click on Commercial and recreational aviation then scroll down to Airworthiness > GA maintenance check flights.

This is the result of AOPA lobbying the Department for Transport (DfT) since the beginning of April, followed by chasing and culminating in this guidance being drafted in the afternoon of  16 April 2020 after a detailed conversation between Martin Robinson,CEO AOPA UK, and the DfT earlier in the afternoon.

AOPA thank the DfT and the CAA for expediting this yesterday (16 April 2020).
