The detection of X-ray narrow spectral features in the 5-7 keV band isbecoming increasingly more common in AGN observations, thanks to thecapabilities of current X-ray satellites. Such lines, both in emission and inabsorption, are mostly interpreted as arising from Iron atoms. When observedwith some displacement from their rest frame position, these lines carry thepotential to study the motion of circumnuclear gas in AGN, providing adiagnostic of the effects of the gravitational field of the central black hole.These narrow features have been often found with marginal statisticalsignificance. We are carrying on a systematic search for narrow features usingspectra of bright type 1 AGNs available in the XMM-Newton archive. The aim ofthis work is to characterise the occurrence of the narrow features phenomenonon a large sample of objects and to estimate the significance of the featuresthrough Monte Carlo simulations. The project and preliminary results arepresented.Comment: 6 pages,4 figures, contributed talk presented at the Workshop "The  multicoloured landscape of compact objects and their explosive origin",  Cefalu' (Sicily), 11-24 June 2006, to be published by AI
