This AD was prompted by an aborted takeoff caused by liberation of small pieces from the HPC stages 1-2 seal teeth and two shop findings of cracks in the seal teeth. This AD requires eddy current inspection (ECI) or spot fluorescent penetrant inspection (FPI) of the stages 1-2 seal teeth of the HPC stages 2-5 spool for cracks. This AD only allows installation of either HPC stator stage 1 interstage seals that are pregrooved or previously worn seals with acceptable wear marks to prevent heavy rubs. We are issuing this AD to detect cracks in the HPC stages 1-2 seal teeth due to heavy rubs that could result in failure of the seal of the HPC stages 2-5 spool, uncontained engine failure, and damage to the airplane.", "2011-12-30", 2011, 12, "https://www.federalregister.gov/documents/2011/12/30/2011-32832/airworthiness-directives-general-electric-company-ge-ge90-110b1-and-ge90-115b-turbofan-engines", "https://www.govinfo.gov/content/pkg/FR-2011-12-30/pdf/2011-32832.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We are adopting a new airworthiness directive (AD) for the products listed above, with certain part number (P/N) high-pressure compressor (HPC) stages 2-5 spools installed.
