& # 39; Unusual cracking & # 39; is detected on Boeing 737 Next Generation aircraft
- Boeing 737 Next Generation aircraft were found to have cracking pickle forks
- Boeing says the problem is isolated and that there are no & # 39; in-service problems & # 39; have been & # 39;
- The 737 NG aircraft captured approximately 35,000 miles when damage was found
- Next Generation models are: 737-700, 737-800 and 737-900.
- Boeing said these cracks are not connected to 737 Max or P-8 Poseidon aircraft
Boeing is trying to figure out what the & # 39; unusual cracking & # 39; on its Next Generation aircraft, while also struggling with investigations after two 737 Max crashes.
During a recent inspection, employees found a severely cracked pickle fork on a Boeing 737NG. The aircraft is relatively young and has registered approximately 35,000 flight cycles when the damage was found.
A pickle fork is the part that helps to attach the fuselage of an aircraft to the wing structure. It helps control the stress, torque and aerodynamic forces that bend the connection between the wings and the body of the jet.
A retired Boeing engineer told KOMO TV: & # 39; It is unusual that there is a crack in the pickle fork. It is not designed to crack like that at all. Period. & # 39;
Boeing says that part of the fleet has a squat section that attaches itself to the hull. An Aeroflot Boeing 737 Next Gen flight is shown
Pickle forks are designed to make more than 90,000 landings and take-offs without tearing, with terrible results if the system fails, KOMO reports. There are four pickle forks on the Boeing 737.
& # 39; No problems were reported during use. In the coming days we will work closely with our customers to implement a recommended inspection plan for certain aircraft in the fleet & # 39 ;, wrote a Boeing spokesperson. & # 39; This issue does not affect 737 MAX aircraft or the P-8 Poseidon. & # 39;
Boeing added that the problem was found in a small number of jets that underwent changes.
The Boeing 737 NG & # 39; s are the models with the designation 737-700, 737-800 and 737-900.

No one was injured by the cracked equipment and, KOMO reports, it is almost certain that the damaged aircraft flew with passengers before it was discovered.
The unnamed engineer added: & # 39; A crack like this looks like a crack in the handle of a coffee cup. You can probably continue to use the cup several times, but there is always a risk that the handle will break and hot coffee will end up on your lap. & # 39;
Until they determine the extent of the problem, it will be difficult for maintenance teams. At present, the government has not instructed mandatory inspections.
Chicago-based manufacturer Boeing has already been examined for the crashes in which 346 people died in Ethiopia and Indonesia.
On Thursday, the National Transportation Safety Board then made recommendations an investigation into the certification of the 737 Max.
The agency has reviewed the evaluation process for the Boeing 737 Max & # 39; s Maneuver Characteristics Augmentation System, a critical system at the heart of both crashes.
