Page 69 - UK Continuing Airworthiness Regulations (Consolidated) 201121

ANNEX I - Continuing Airworthiness Requirements

1. If the continuing airworthiness of the aircraft is not managed according to an Appendix I
Continuing airworthiness contract, the aircraft should be considered to be outside a
controlled environment. Nevertheless, such contract is not necessary when the operator
and the CAMO are the same organisation.
2. The fact that limited pilot-owner maintenance as defined in M.A.803(b) is not carried out
and released by an approved maintenance organisation does not change the status of an
aircraft in a controlled environment providing the CAMO under contract has been informed
of any such maintenance carried out.
M.A.901(c)2 AMC, M.A.901(e)2 AMC Aircraft airworthiness review
& M.A.901(f) AMC When the aircraft has remained within a controlled environment, the extension of the validity of the
airworthiness review certificate does not require an airworthiness review but only a verification of the
continuous compliance with M.A.901(b).
It is acceptable to anticipate the extension of the airworthiness review certificate by a maximum of 30
days without a loss of continuity of the airworthiness review pattern, which means that the new
expiration date is set up one year after the previous expiration date. This anticipation of up to 30 days
also applies to the 12 month requirements shown in M.A.901(b), meaning that the aircraft is still
considered as being in a controlled environment if it has been continuously managed by a single
organisation and maintained by appropriately approved organisations, as stated in M.A.901(b), from
the date when the last airworthiness review certificate was issued until the date when the extension is
performed (this can be up to 30 days less than 12 months).
It is also acceptable to perform the extension of an airworthiness review certificate after its expiration
date, as long as all the conditions for the extension are met. However, this means the following:
- The aircraft could not fly since the airworthiness review certificate expired until it is
extended, and
- The new expiration date (after extension) is set one year after the previous expiration date
(not one year after the extension is performed).
M.A.901(d) AMC Aircraft airworthiness review
The recommendation sent by a CAMO or CAO to the CAA should be in English.
The recommendation sent to the CAA should contain at least the items described below:
(a) General information
- CAMO information
- owner/lessee information
- date and place where the document review and the aircraft survey were carried out
- period and place the aircraft can be seen if required by the CAA
(b) Aircraft information
- registration
- type
- manufacturer
- serial number
- flight manual reference
- weight and centre of gravity data
- maintenance programme reference
(c) Documents accompanying the recommendation
- copy of registration papers
- copy of the owners request for a new airworthiness review certificate
(d) Aircraft status
- aircraft total time and cycles
- list of persons or organisations having carried out continuing airworthiness activities
including maintenance tasks on the aircraft and its components since the last
airworthiness review certificate
(e) Aircraft survey
- a precise list of the areas of the aircraft that were surveyed and their status
(f) Findings

action carried out
(g) Statement
A statement signed by the airworthiness review staff recommending the issue of an
airworthiness review certificate.
The statement should confirm that the aircraft in its current configuration complies with
the following:
- airworthiness directives up to the latest published issue, and;
- type certificate datasheet;
- maintenance programme;
- limitation for lifelimited parts and timecontrolled components;
- the valid weight and centre of gravity schedule reflecting the current configuration of
the aircraft;
