BAE Systems airplanes need new maintenance rules, again

The US aviation regulator is proposing to update an existing rule for BAE Systems Model 4101 airplanes. This means the maintenance and inspection programs for these specific aircraft will need to be revised with new or stricter limitations.

This is a small, specific update to an existing safety rule. It means that the previous safety measures for these particular airplanes were not enough. Aircraft operators will need to spend more time and money to keep these planes flying safely.
