India's aviation regulator flags concern with the Boeing 737 Max aircraft in service with three Indian airlines at a time when there have been international headlines over an Alaska Airlines aircraft which had an explosive decompression on board during a flight which resulted in an emergency exit being blown off the aircraft. The incident in India is not related to the Alaska Airlines incident but the regulator, the DGCA, has said that in the course of inspections, a washer was missing in the critical tail assembly of one of the aircraft. Meanwhile, United Airlines, one of the largest airlines in the world, has said that they have found loose parts on multiple grounded aircraft - this is all bad news for Boeing amid concerns on the manufacturing standards of an aircraft that has had a poor safety reputation.
