Investors may be overreacting, according to Thomas Hayes, chairman and managing member at Great Hill.

Following the revelation, shares of Boeing supplier Spirit Aerosystems fell more than 20% on Friday.

But he went on to say, “I can understand why it’s a shoot first and ask questions later because Boeing has impaired their trust with investors over the constant and repeated errors over the last few years.”

Following the incidents, Boeing’s 737 Max was grounded for more than a year.

In addition, the company has experienced a number of supply problems as it strives to increase output and get out from under the shadow created by the scandal.

Due to a difficulty with their data processing, the company was forced to cease widebody 787 Dreamliner deliveries in February. Last month, US transportation regulators gave Boeing the go-ahead to commence deliveries.

The new problem, which affects the 737 Max family of aircraft, including the Max 7, Max 8, and Max 8200 aircraft, as well as Boeing’s P-8 Poseidon maritime surveillance aircraft, Boeing stated affected a “significant number” of undelivered jets in production and in storage. Some of the involved aircraft are already in use.

According to the business, checks will be conducted and fittings would be changed “where necessary” in cooperation with regulators.

The fleet currently in service can continue to operate safely, the airline stated, adding that there is no imminent threat to flight safety.
