51-10-02 Repair Criteria and Limits
I M P O R T A N T All damage of composite parts must first be classified
prior to repair. Refer to Chapter "51-10-01 Damage
Classification".
I M P O R T A N T Only the Damages Classes 2, 3 and 4 may be repaired
by qualified personnel. In case of Damage Class 1 it
has to be contacted EXTRA-FLUGZEUGBAU GmbH.
The decision whether to repair or replace a major unit of
structure will be influenced by factors such as time and labor
available, and by comparison of labor costs with the price of
replacement assemblies. Past experience indicates that
replacement, in many cases, is less costly than major repair.
Certainly, when the aircraft must be restored to its airworthy
condition within limited time, replacement is preferable.
