Not fully understanding the sequence of the test routine, the wing and rudder came into contact resulting in minor to moderate damage to both. Though an engineering solutio

Though an engineering solution prevented the need to replace the rudder,
5、the schedule impact was not trivial while determining the extent of the damage and adequacy of the solution. Lesson(s) Learned: Deviations in approved testing procedures, no matter how insignificant, can result in oversights and assumptions that could lead to serious project schedule and cost impact
6、s. Recommendation(s): Follow approved testing procedures without deviation.
