Boeing actually wanted to significantly increase the production rate of the B737 Max series. Nothing will come of this - at least for the time being - because the Civil Aviation Authority (FAA) prohibits the manufacturer from increasing any production.

The Boeing 737 Max series can look back on an extremely inglorious history: after two total losses, a worldwide flight ban was imposed. Little by little, serious defects and sloppiness came to light. There is also an accusation that the manufacturer did not adequately inform civil aviation authorities or customers about safety-related matters. After extensive testing and numerous improvements, the FAA approved the Max-8 and Max-9 series. However, the Max-7 and Max-10 are still waiting for certification.

The FAA said at the time that the Boeing 737 Max series was the type of aircraft that had been tested more extensively than any other aircraft. It is the safest civil aircraft in the world. Earlier this month, a Boeing 737-Max-9 operated by Alaska Airlines lost a blade during climb. The FAA immediately ordered a flight ban and the inspection of identical jets. Serious defects were found. For example, Alaska Airlines and United Airlines report many loose bolts and screws.

The FAA directive stipulates that the affected aircraft must be repaired before they can be used again. All loose screws, bolts and other defects must be repaired. The fastening elements of the blades located in front of unnecessary emergency exits must be checked separately and tightened if necessary.

The matter has another consequence for Boeing: they actually wanted to increase the monthly production rate of the B737 Max series to 38 machines per month. Most recently it was around 31 copies per month. It should gradually go up to 42 jets per month and then to 47. The FAA is now putting a stop to this.

The US Civil Aviation Administration has prohibited Boeing from carrying out its planned increase in production rates. No further “expansion” will be approved – at least for the time being. This is probably also due to the fact that the FAA is taking a close look at the production processes. At the moment it is not foreseeable to what extent the authority's order will cause further delivery delays. It is to be expected that one or two carriers will soon have their say in this regard.
