The May crash at Hanscom Field killed seven people and prompted the maker of the Gulfstream IV to issue safety warnings about its use. Gulfstream Aerospace Corp. is warning pilots that a feature designed to prevent crashes is not fail-safe and that operators must rigorously follow a flight checklist before taking off. The warning comes in the wake of a May crash at Hanscom Field that killed seven people, including Philadelphia Inquirer co-owner Lewis Katz. In a letter dated Aug. 18, the maker of business jets issued a caution about the locking system on the Gulfstream IV, the model that crashed at Hanscom. That mechanism, known as a gust lock, protects the plane from damage when it is on the ground. But the lock must be released for aircraft to get off the ground.
