I draw the attention of all to two 737-800 events shown on AvHerald. The first, posted
here, seems extremely serious. There is another on AvHerald
here on 15/1. I note the 'tech check revealed nothing' on the 15/1. Reminds me of a snag I raised on a BA734 which had fumes at full power. 'Ground tested found satis'. Guess what power they ground ran it at...................?
If these fumes are the known oil haze, possibly carcinogenic, these events need to be taken really seriously.
