Good day all. I was browsing AA.com and was looking at the airplane layout of the757 Domestic and found this interesting note at the bottom of the page:
Note: Due to a recent issue involving a powerport on an American Airlines Boeing 757, the American Airlines team will proactively deactivate all powerports on the domestic fleet. The deactivation will begin on Wednesday, September 1, 2010, as the team inspects all 104 aircraft. It is yet to be determined how long the powerports will be deactivated. We realize this is an inconvenience and the issue will be resolved as quickly as possible.
Is anyone aware as to the issue that arose for the reason the powerports are being deactivated?

757 Powerport System Messaging
Nov. 5, 2010
In October, American Airlines began upgrading the majority of its Boeing 757 fleet, which includes the installation of new seats, new cabin interiors, and updated in-flight entertainment systems throughout the aircraft. American also is installing new AC powerport systems, which will allow customers to easily plug in their laptops, smartphones and other electronics – just as they would at home.
The new AC powerport system will ultimately replace the 12V DC powerports. Until that time, an updated DC system will be installed starting mid-2011 as a replacement to the existing deactivated DC system. Once installed, the new AC powerport system will eliminate the need for passengers to carry a DC power adapter.
We realize this is an inconvenience to our customers, however, the safety of our customer and crew is our highest priority. We are working to remedy the situation as quickly as possible
•In August 2010, an issue was discovered with a DC powerport on a domestic 757 aircraft. To ensure the safety of our customers and flight crew, the aircraft returned to the airport, so it could be inspected. The aircraft was repaired before it went back into service.
•As a proactive measure, DC powerports were deactivated on 104 domestic 757s, as Maintenance & Engineering determined the potential scope of the issue.
•Twenty aircraft were not affected by the deactivation decision, as they had either been recently reconfigured for International Flagship Service or were already in the process of being upgraded with AC powerports.
•It is estimated that all of the remaining 104 757s will either receive new AC powerport systems or will have their DC powerport systems updated by mid-2012.
