E4.3 ‘Other Experienced Applicants’
Aircraft maintenance experience gained outside a civil aircraft maintenance environment can include experience gained in armed forces, coast guards and police.
E4.4 Experience Required
B2 applicants must demonstrate 1 years experience in a civil maintenance environment appropriate to the category applied for, where the applicant can provide satisfactory evidence of working in one of the above disciplines (E4.3).
Where does it say 145 not acceptable? I would try again because not all in licensing know what they are talking about.
