US regulators are investigating after an incident during which a Boeing 737 Max 8 flown by Southwest Airlines rocked aspect to aspect whereas in air, in a doubtlessly harmful motion generally known as a “Dutch roll”.

It is one among two new inquiries involving Boeing planes that the Federal Aviation Administration (FAA) has just lately confirmed.

The company can also be concerned after Boeing reported studying of probably falsified paperwork used to certify titanium utilized in its planes.

The points have emerged at a time when the security report of Boeing planes is below intense scrutiny.

Boeing referred questions in regards to the Southwest flight to the airline, which didn’t instantly remark.

Boeing stated the difficulty involving titanium was “industry-wide” involving shipments from a restricted set of suppliers.

It stated checks carried out to this point point out that the proper alloy was used, regardless of the false documentation.

It stated it sourced the steel individually from its provider and it believed a small variety of components had been affected.

“To ensure compliance, we are removing any affected parts on airplanes prior to delivery. Our analysis shows the in-service fleet can continue to fly safely,” the company said.

The New York Times, which first reported the issue, said a supplier to Spirit Aerosystems, which makes parts for Boeing and European plane-maker Airbus, started looking into the issue after noticing holes from corrosion.

Spirit, which had alerted the two manufacturers to the problem earlier this year, said more than 1,000 tests had been completed on the suspect parts, which had been removed from production.

“It is the paperwork that had been counterfeit, not the titanium,” spokesman Joe Buccino said. “The downside is we have misplaced traceability.”

The FAA said Boeing had issued a bulletin to suppliers to be on the alert for counterfeit records and that it was probing the scope of the issue.

The so-called Dutch roll, reportedly named after the movement in a gliding ice skating technique attributed to the Netherlands, occurred on a 25 May flight from Phoenix, Arizona to Oakland, California.

The FAA said the aircraft regained control and no one on board was injured but the plane suffered “substantial” damage.

A post-flight inspection revealed significant damage to a unit that provides backup power to the rudder.

“Dutch roll will be disagreeable however the 737 displays comparatively benign traits. The time elapsed because the incident, and the absence of airworthiness motion on the fleet, recommend that this can be a one-off, not one other widespread downside for Boeing,” said Tim Atkinson, a former UK accident investigator turned consultant.

Safety campaigners have raised alarm about the quality of recent planes produced by Boeing.

An incident in which a panel broke off a plane in mid-air in January reignited concerns, sparking lawsuits and increased oversight by Boeing.

Boeing last month presented the FAA with an action plan aimed at resolving the issues.
