Specialized services

COMPOSITE MATERIAL

SEMAN, being a Maintenance Organization recognized nationally and internationally, expands its maintenance capabilities by implementing specialized workshops such as the Composite Material Workshop, where is carried out the repair/ alteration of mobile surfaces whose composition is made of composite materials. Also perform bonding of aircraft structures in accordance with the national and international Regulations parts 43.145 and 14, CFR parts 121, 135, 121,379 and 135,437. SEMAN as a Maintenance Organization works along with the aircraft manufacturer, the OEM (Original Equipment Manufacturer) and the Federal Aviation Administration in order to determine which documentation used in the repair or alteration is correct since much of the information required is found in the Manufacturer’s Maintenance Manual or in the Structural Repair Manual.

SEMAN has the Advisory Circular AC 43-214 in force “Repair stations for composite materials structures”
