May 23 (Reuters) - Boeing CFO Brian West said Thursday that commercial jet deliveries won't step up in the second quarter compared with the first three months of the year as the company reckons with production quality issues.

West also told the Wolfe Research Global Transportation and Industrials Conference the planemaker’s jet deliveries to China were delayed in recent weeks due to a Chinese regulatory review of batteries powering the cockpit voice recorder, confirming an earlier Reuters report.

The company's jet production has slowed dramatically in the face of increased scrutiny from regulators, airlines and lawmakers following a January incident when a door plug blew off an Alaska Airlines jetliner while in mid-air. (Reporting By Allison Lampert)
