Haas is shipping a new strengthened front wing for its Formula 1 car to the Barcelona test on Tuesday following Romain Grosjean's failure on the first day.
Grosjean's front wing broke off on the start-finish straight before lunch when the support pillars broke – for reasons that the American outfit has not yet fully found out.
While the team was able to continue running, albeit for shorter distances so it could monitor its spare wing, it has elected to ship a new design from its Banbury factory.
Team principal Gunther Steiner said: “We evaluated what was wrong and we are still checking, but we fixed one up for the afternoon.
“We went out there, but we just did short runs to always keep an eye on it. We get a complete fixed wing tomorrow for 8am – strenghtened.”
He added: “We don't know why it broke but we know where to reinforce it. We have a solution that we know we can keep running.”
Although the wing failure was a frustration for the team, Steiner said early running of the new VF-16 had been encouraging up until that point – and there were at least some good lessons learned.
“With the team being new it is quite difficult,” he explained. “A simple operation for Ferrari or Mercedes or one of the teams that are here a long time; it is new for us but not so easy for us.
“It is a situation we handled professionally. We got a solution, we went out again and we did some running. We are still gathering cooling data, brake data, but we got quite a lot done anyway.
“As much as we are unhappy, we are happy because we got work done. It would have been nice to do 70-80 laps instead of 31, but sometimes that is why we are here to learn about the car and test.”
Regarding the overall form of the car, Steiner said: “I think we are pretty happy. It is more a question for the driver I would say - what he feels about the car, or how he feels confident.
“But we didn't discover any big issues, it is not like overheating or anything like this. We are in control and we are happy with the package.”
