The 2019 skydiving plane crash in Mokuleia 鈥 one of the nation鈥檚 worst civil aviation accidents of the past decade 鈥 probably occurred due to an 鈥渁ggressive takeoff maneuver鈥 by the pilot, according to new findings released Tuesday by the National Transportation Safety Board.

The NTSB listed several other contributing factors in the crash, including the pilot鈥檚 lack of training and experience with the Beechcraft B90 plane, the skydiving company鈥檚 failure to keep the plane airworthy, and lax regulation of such flights by the Federal Aviation Administration.

Those findings into the crash, which killed all 11 people on board moments after take off at Dillingham Airfield, were briefly outlined in the NTSB鈥檚 of the nation鈥檚 skydiving flights and air tours.

A final and more detailed report discussing the crash鈥檚 probable cause has not been released yet – NTSB officials said Wednesday that it will be issued sometime in the next few weeks. So far, there鈥檚 been a preliminary report and a series of 鈥溾 released.

The report that the NTSB released Tuesday was broader in scope. The Mokuleia crash — and the findings into what caused it — were among eight total crashes that the board cited as it renewed its call for stricter operations, training, maintenance and safety standards from the FAA.

Tuesday鈥檚 report further revealed that the Beechcraft, operated by Oahu Parachute Center, had a 鈥渢wisted left wing鈥 that also contributed to the crash because it 鈥渞educed the airplane鈥檚 stall margin.鈥

鈥淐ontributing to the pilot鈥檚 training deficiencies was the FAA鈥檚 lack of awareness that the pilot鈥檚 flight instructor was providing substandard training,鈥 the report added.

In fact, the NTSB has voiced concerns for more than 30 years over what it views as lax and uneven oversight of skydiving and air tour flights, both of which are prevalent in scenic Hawaii.

Those calls have often been rebuffed, however, by the FAA and the general aviation industry, which worries that smaller tour operators will go out of business if the standards grow too rigid.

Currently, skydiving flights and many air tours are covered by general aviation regulations, known as Part 91. But NTSB officials argue that such commercial flights should be covered under , which would require more frequent, rigorous aircraft maintenance and pilot training.

‘Too Many Cowboys Cutting Too Many Corners’

Several employees and pilots at the airfield interviewed by NTSB investigators said that the pilot during the crash, Jerome Renck, would often perform aggressive maneuvers upon takeoff from the North Shore airfield and its beach-adjacent runway.

A SkyDive Hawaii pilot told investigators that Renck 鈥渨ould rotate the airplane and bank simultaneously,鈥 according to the NTSB鈥檚 factual reports. 鈥淚t looked like the pilot was trying to get the most out of the airplane when he was using a high pitch and bank, clearing the ironwood trees that lined the highway by about 50 feet.鈥

Renck also piloted the flight prior to the one that crashed, and an experienced parachutist on the prior flight told investigators that during takeoff the airplane banked 鈥渓eft lower than what he was accustomed to seeing.鈥

A less-experienced parachutist also on the previous flight told investigators that he too noticed an 鈥渁ggressive turn at departure,鈥 and that other passengers on board told him that was not normal. A third parachutist aboard that flight called the takeoff “a little ‘spicey’ (sic) for his liking,” according to the report.

However, one of Renck鈥檚 pilot colleagues at Oahu Parachute Center told investigators that it was 鈥渘ot unusual鈥 for pilots to bank hard on takeoff in order to avoid the landing zone for parachutists.

Former Oahu Parachute Center pilots told NTSB investigators that 鈥渢here was no training curriculum,鈥 nor were there training or procedures manuals. One former pilot called the training there 鈥渁 joke.鈥

鈥淭here was no formalized training since there was no money to take the airplane out of service for training flights,鈥 the NTSB factual reports state.

Pilots 鈥減rimarily trained by viewing the King Air Academy videos on YouTube and not hands-on training,鈥 the reports added, referring to the series of Beechcraft planes.

Tuesday鈥檚 NTSB report and its recommendations 鈥渉ighlight the critical need to further regulate our air tour industry,鈥 U.S. Rep. Ed Case said in an email. He鈥檚 repeatedly introduced legislation that aims to do that.

鈥淭he FAA鈥檚 current regulations simply are not keeping our skies and ground safe,” Case said.” There are just too many cowboys cutting too many corners with too little real oversight. The FAA must finally implement what the NTSB has urged over too many fatal crashes.鈥
