    Default R.A.F Aircraft - WWII categories of repair

    Could someone check my memory of the different categories of aircraft damage repair used in WWII ? Thank you.

    Cat A - Repairable at front line/first line - Squadron engineering
    Cat B - Repairable at second line - Station engineering.
    Cat C - Repairable at third line - M.U. Maintenance Unit - stripdown - rebuild
    Cat D - Un-repairable - useable parts recovered to service other aircraft.
    Cat E - Un-repairable - aircraft "Written off strength" / "Struck off charge" - scrap

    Norman,

    I saved the following table of damage categories submitted by a poster to this forum some time ago; I cannot link to the original posting and can not vouch for its provenance.

    R.A.F. Aircraft - Damage Categories Pre 1941

    Cat.U Undamaged
    Cat.M(u) Capable of being repaired on site by the operating unit
    Cat.M(c) The repair is beyond unit capacity.
    Cat.R(B) Repair on site is not possible; the aircraft must be dismantled and sent to a repair facility.
    Cat.W Write-Off

    1941 - 1952

    Cat.U Aircraft Undamaged
    Cat.A Aircraft can be repaired on site
    Cat.Ac Repair is beyond the unit capacity, i.e. may be repaired on site by another unit or contractor
    Cat.B Beyond repair on site, i.e. repairable at a Maintenance Unit or at a contractor's works
    Cat.C Allocated to Instructional Airframe duties
    Cat.E Aircraft is a write-off
    Cat.E1 Aircraft is a write-off but is considered suitable for component recovery
    Cat.E2 Aircraft is a write-off and suitable only for scrap
    Cat.E3 Aircraft is burnt out
    Cat.Em Aircraft is missing from an operational sortie (missing aircraft categorised "Em" after 28 days)

    In addition to the above the cause of the damage is sometimes indicated by a prefix or suffix, thus;
    FA Flying Accident
    FB Operational Loss
    GA Ground Accident
    T Technical Cause
    EA Enemy Action

    Hi Ken

    the information appears to come from the rafmuseum website:
