| 2016-15904 | Airworthiness Directives; The Boeing Company Airplanes | Rule | We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports of a manufacturing oversight, in which a supplier omitted the required protective finish on certain bushings installed in the rear spar upper chord on horizontal stabilizers, which could lead to galvanic corrosion and consequent cracking of the rear spar upper chord. This AD requires an inspection or records check to determine if affected horizontal stabilizers are installed, related investigative actions, and for affected horizontal stabilizers, repetitive inspections for any crack of the horizontal stabilizer rear spar upper chord, and corrective action if necessary. We are issuing this AD to detect and correct cracking of the rear spar upper chord, which can result in the failure of the upper chord and consequent departure of the horizontal stabilizer from the airplane, which can lead to loss of control of the airplane. | 2016-07-08 | 2016 | 7 | https://www.federalregister.gov/documents/2016/07/08/2016-15904/airworthiness-directives-the-boeing-company-airplanes | https://www.govinfo.gov/content/pkg/FR-2016-07-08/pdf/2016-15904.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes.
