Foreign Object Damage (FOD) aviation

Foreign Object Damage is any damage attributed to a foreign object that can be expressed in physical or economic terms that may or may not degrade the product's required safety and/or performance characteristics.

Foreign Object Damage (FOD) usually happens when objects are ingested into jet engines powering military or civil aircraft. Under extreme conditions, FOD can lead to severe structural damage. More commonly it produces local impacted sites of the fan and compressor airfoils, lowering fatigue life of these components. FOD is a prime cause for maintenance and repair in aircraft engines.

  

There are many types of foreign object damage and these are 5 of them:
1-birds strikes, 2-tools on floor, 3-dust, 4-snow storm, 5-insects.

1-Birds strikes are most of the FOD that occur, they happen when the airplane take off and a group of birds flying in the other directions which will increase the momentum between them and make the strike so hard which will cause damage to the airplane and it might make the airplane crash.

2-The tools that have been forgotten by the maintenance engineers could cause a serious FOD, which will be sucked in the engine when it is turned on, this will cause the engine blades to break, or may cause the engine to explode.

3-Dust can cause a serious FOD on the ground and in the air. In the ground it can get in the engines and damage its parts, In the air it can damage the engines and it can block the vision of the pilots and the co-pilots and cause them to crash.

4-Snow storms and blizzards can cause the airplanes to have a huge FOD, which will increase the weight of the aircraft, freeze most of it parts, and might destroy the engines.

5-Insects FOD mostly occur when the aircraft is at the workshops, if the engineers didn’t block the engines by intake screens, insects may enter the engine and have nests in the engine and destroy it.

To prevent FOD there are some methods

Clean the immediate area when work cannot continue.

Clean the immediate area when work debris has the potential to migrate to an out of sight or inaccessible area and cause damage and/or give the appearance of poor workmanship.

Clean the immediate area after work is completed and prior to inspection.

Clean at the end of each shift.

If you drop something or hear something drop - pick it up!

Trip to Brunei

About 30 years ago Hedley, his wife Mary and his elder daughter Katie, visited the Niah Caves in East Malaysia.

They started their journey from Brunei, Bandar Seri Begawan. They started their journey in the early morning, they traveled by car, ferry and small boat, and they finally arrived at dusk to the government guest house.

When they entered the caves they saw some men climbing the bamboo poles in order to scrape birds' nests off the roof of the caves, because they wanted to sell it to the Chinese, because Chinese think that it is good for their health when they make it into soup.

The next day they returned to Brunei after lunch.

The good thing that happened to them in their journey is that they were able to watch the people climbing the poles for the nests, and the bad thing about the journey is that Hedley damaged his car by accident and the reverse gear didn’t work but they managed it.

Amy Lee (Evanescence Singer/Pianist)

It's been nearly four years since Evanescence wrapped the tour in support of their last album, The Open Door. In that time, singer Amy Lee has been hard at work doing anything but fronting a globally successful rock act. Sure, she wrote some songs along the way, but mostly, her focus was on being a normal person. And, yes, she enjoyed every minute of it and she said that she wanted to teach music to childrent to try to avoid her original life.

And considering how hard she worked at avoiding Evanescence, it's ironic that all it took was a single show with the band, a 2009 warm-up gig for a headlining spot at the Maquinária festival in Brazil,  to remind her of just how much she missed her former life. And from that moment on, things changed.

So, recharged, Evanescence did just that, heading to Blackbird Studio in Nashville to work with producer Nick Raskulinecz on the follow-up to The Open Door. They've nearly finished.  Lee said there are currently 16 songs at or near completion. Their longtime label, Wind-up Records announced that the album would be hitting stores October 4.

And it's difficult for Lee to describe just how the new songs sound :it's epic, it's dark, it's big, it's beautiful ... all of those things, she laughed. She knows exactly how they make her feel ,and after such a long time away from the group, that's more important to her than anything else.

The name of 1 of thier new songs is "What You Want".
