NTSB narrative
While climbing through 26,000 feet, the airplane began to pitch up and down at a fast rate. The captain took control of the airplane and leveled off. The airplane continued to pitch up and down, the autopilot was engaged, and the airplane stabilized. The airplane was slowed to 230 knots and the autopilot was turned off. The pitch oscillations began again. The crew declared an emergency and returned to Newark International Airport, Newark, New Jersey, and landed without incident. The left inboard elevator parallel engage solenoid shut off valve was replaced and no further discrepancies were noted with the system. Examination of the faulty valve revealed that a short was found when tested between coil 1 and coil 2. Disassembly of the unit revealed that hydraulic fluid was found underneath the case assembly and around the coil assembly. The examination also revealed that the orange colored lead to coil 1, and the brown colored lead to coil 2 had fused together through the insulation and caused the electrical short. It could not be determined as to how the hydraulic fluid entered the valve, or if the fluid contributed to the electrical short. At the time of this report, Boeing was in the process of establishing a components team to research the possibility of fluid contamination in these valves.
Probable cause
a short in the left inboard elevator parallel engage solenoid valve for undetermined reasons.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
