Uvalde, Texas-based Sierra Industries has been certified by Mexico’s Dirección General de Aeronáutica Civil (DGAC) to inspect, repair and modify Mexican-registered aircraft, from piston singles to business jets.
Operating out of a 90,000-sq-ft facility, Sierra Industries also specializes in modifying older Cessna Citations for better performance. Additionally, the MRO offers PMA parts manufacturing, in-house avionics support and on-field paint and interior specialists.
Next month, the Mexican government is expected to issue a ruling restricting maintenance services for Mexican-registered aircraft to facilities located within Mexico. The DGAC has said it intends to exempt the limited number of currently approved DGAC-certified facilities outside the country’s borders. Sierra Industries is located on Uvalde’s Garner Field Airport approximately 50 miles from the Mexico-Texas border and less than 250 miles from Monterrey. It has an existing customer base in Mexico for mod programs such as the FJ44 re-engining and Eagle/Longwing Citation airframe upgrades. The DGAC certification ensures that those owners can continue to use Sierra.
