A three-year-old internal Boeing survey found that one in three employees felt “potential undue pressure” to approve their own aircraft safety features, The Wall Street Journal reported Sunday.
The 2016 survey found that some 29% engineers felt pressure from their managers to certify for the Federal Aviation Administration plane systems that they had designed themselves, reported the Journal’s Andrew Tangel and Andy Pasztor, who reviewed the survey.
The survey also highlighted the dangers of having Boeing employees develop as well as certify their own work, noting that “conflict can occur” in times like this, the Journal added.
Workload and schedule were cited as major causes for the stress. More than 80% of respondents did add, however, that they were confident that they could address concerns about undue pressure, according to the Journal.
The House Committee on Transportation and Infrastructure is currently scrutinizing this survey as part of its investigation into the design and development of the Boeing 737 Max, which includes scrutiny into how the plane got FAA approval.
The House probe came after two deadly crashes that killed a total of 346 people within five months of each other.
The Committee on Transportation and Infrastructure, Boeing, and the FAA have not yet responded to Business Insider’s requests for comment on the survey and Boeing’s work culture.
Boeing has faced increased pressure in recent days, after leaked messages between its top chief technical pilot and his colleague in 2016 — around the same time employees were answering the survey — suggested that the company misled the FAA about the 737 Max’s safety issues.
A panel of air-safety regulators earlier this month slammed the FAA’s “inadequate awareness” of Boeing’s anti-stall software, which has been blamed for the two crashes.
All Boeing 737 Max planes around the world remain grounded, with airlines scrambling to work out how to tell passengers they’re flying on a 737 Max when they return to service.
The Committee on Transportation and Infrastructure is scheduled to hold a hearing on the “design, development, and marketing” of the Boeing 737 Max on October 30.
