by W.J.C Speller
Notes
British Empire Aeronautical Ground Engineers or simply “Ground Engineers” (1919 -1952) were Civilian “Aviation Safety Inspectors” specially trained and educated in aeronautics at a British Technical Institute (known as a University today) and once having completed their “Apprenticeship in the Trade” and performing aeronautical Inspection duties as a “candidate Engineer” under the supervision of a Licensed Ground Engineer, they were subsequently examined by the Air Ministry‘s “A.I.D – Technical department” and if found acceptable, licensed by the British Government as being qualified to inspect and to certify the mechanical systems and the structural airworthiness of an aircraft of the period. These persons were employed in Manufacturing, Overhaul, Major Repair, Overhaul and Maintenance of aeronautical products.

Five (5) types of Ground Engineer Licenses were issued, identified using a Letter system of categories:

Ground Engineer category “A” License: Inspection and Certification of Aircraft before Flight / Minor repairs / Minor modifications.

Ground Engineer category “B” License: Inspection and Certification of Aircraft during Manufacture and after Overhaul / Major repairs / Major modifications.

Ground Engineer category “C” License: Inspection and Certification of Aero-Engines before Flight / Minor repairs / Minor modifications.

Ground Engineer category “D” License: Inspection and Certification of Engines during Manufacture and after Overhaul / Major repairs / Major modifications.

Ground Engineer category “X” License: Inspection and Certification of Electrical and Wireless Equipment of Aircraft.
