(In July 10 story, corrects paragraph 2 to show Boeing makesboom, not Cobham)
FARNBOROUGH, England, July 10 (Reuters) - Boeing Co is well into testing of a modification to the refueling boom onits troubled KC-46A tanker program and is seeing "positiveresults," the head of the company's defense division said onSunday.
Leanne Caret, chief executive of Boeing Defense, Space &Security, told reporters the company was encouraged by tests ofa modified boom built by Boeing after a software fix failed toaddress instability issues that cropped up while delivering fuelto large aircraft.
The changes did not amount to a redesign of the boom, andwould not require additional certification, she told reporters.
Caret said prospective Middle Eastern fighter jet customerswere "hanging in there with us," despite delays in getting U.S.approval for several large F-15 and F/A-18E/F fighter jet sales.She said the process was clearly taking longer than the companywould like, but still hoped to get the deals approved.
