Virgin has been forced to park its VR-01 for the rest of today's test session at Jerez due to a shortage of spare parts.
Timo Glock was driving this morning when the front wing came off and the debris on the track caused a red flag.
The German returned to the pits but the team does not yet have enough spare parts for him to get back out today.
"This morning we experienced a front wing mounting problem which caused the wing to come off the car at the beginning of a run," said Virgin technical director Nick Wirth in a team statement.
"Unfortunately, we're missing one or two spare parts which will hopefully arrive this evening, so we won't be able to run for the rest of the day."
The team is hoping to get the car back out on track on Friday morning.
"In the short amount of running that we've achieved so far, we are very encouraged by what we've seen and we have gathered some vital aero data which is very much in the range of what we were predicting. We look forward to resuming the programme tomorrow morning."
Glock completed 11 laps today and circulated five times yesterday, when Virgin became the first of Formula 1's four new teams to get its car out on track in an official test.
