AMAC Aerospace Completes Five Boeing BBJ 737 MRO Programs

AMAC Aerospace has completed concurrent maintenance and refurbishment programs on five Boeing BBJ 737 aircraft at its facility in Basel, Switzerland.

In a press release issued on August 10, 2026, the company detailed the varied scopes of work across the five airframes, demonstrating the maintenance, repair, and overhaul (MRO) provider’s capacity to handle simultaneous heavy inspections and interior upgrades for narrow-body VIP aircraft.

Scope of Boeing BBJ 737 maintenance

The maintenance packages ranged from routine flight-hour checks to extensive C checks and cabin refurbishments. According to the company, the specific work scopes included:

• Aircraft 1: A 1,000-flight-hour check performed alongside A, B1, and B2 inspections.
• Aircraft 2: B2 and B3 inspections.
• Aircraft 3: A B2 inspection combined with a water heater replacement.
• Aircraft 4: Extensive heavy maintenance featuring 1C and 2C inspections, a complete landing gear overhaul, and cabin interior work including seat refurbishment and galley countertop replacement.
• Aircraft 5: A standard B check.

Recent VIP aircraft redeliveries in Basel

The completion of these five aircraft follows a steady volume of Boeing Business Jet work at the Swiss facility. On February 23, 2026, AMAC Aerospace announced the redelivery of two other Boeing BBJ 737 aircraft following maintenance. One of those airframes, operated on behalf of a head of state, underwent A1, A2, and three-year inspections, along with a windshield replacement.

AirPro News analysis

The ability to process five Boeing BBJ 737s concurrently underscores the scale of AMAC Aerospace’s Basel operations. VIP aircraft maintenance requires specialized interior handling capabilities alongside standard commercial heavy maintenance approvals. By executing simultaneous C checks, landing gear overhauls, and bespoke cabin refurbishments, AMAC reinforces its position in the highly specialized VIP and head-of-state MRO market, where operators prioritize facilities that can minimize downtime by combining technical inspections with interior upgrades.
