Investing.com -- Top aerospace companies, including Boeing (NYSE: BA ) and GE Aerospace (NYSE: GE ), are examining their supply chains to understand the potential effects of a major fire that occurred last week at a parts factory in the Philadelphia area, Reuters reported Thursday. The fire, which lasted several days at the SPS Technologies’ factory, has raised concerns across the industry.

The fire could lead to additional pressure on the already strained aerospace supply chain. The companies are now trying to identify alternative sources of production to replace the lost capacity and also to locate spare parts.

Boeing and France’s Safran (EPA: SAF ) have reached out to suppliers to inquire about the possible impact of the fire, according to letters seen by sources. The fire did not result in any fatalities but has added to a series of supply chain setbacks in the aerospace industry.

The factory, which is about the size of a stadium, played a crucial role in producing key parts. Some industry observers have warned that the loss of this facility could further hinder the industry’s capacity to increase output.

Among the products manufactured by SPS Technologies are titanium fasteners used in the assembly of carbon-fiber jets, such as the Boeing 787 and Airbus A350.
